Principles of Political Economy with some of their Applications to Social Philosophy

The gross profits from capital, the gains returned to those who supply the funds for production, must suffice for these three purposes. They must afford a sufficient equivalent for abstinence, indemnity for risk, and remuneration for the labour and skill required for superintendence. These different compensations may be either paid to the same, or to different persons. The capital, or some part of it, may be borrowed: may belong to some one who does not undertake the risks or the trouble of business. In that case, the lender, or owner, is the person who practises the abstinence; and is remunerated for it by the interest paid to him, while the difference between the interest and the gross profits remunerates the exertions and risks of the undertaker.
*93 Sometimes, again, the capital, or a part of it, is supplied by what is called a sleeping partner; who shares the risks of the employment, but not the trouble, and who, in consideration of those risks, receives not a mere interest, but a stipulated share of the gross profits. Sometimes the capital is supplied and the risk incurred by one person, and the business carried on exclusively in his name, while the trouble of management is made over to another, who is engaged for that purpose at a fixed salary. Management, however, by hired servants, who have no interest in the result but that of preserving their salaries, is proverbially inefficient, unless they act under the inspecting eye, if not the controlling hand, of the person chiefly interested: and prudence almost always recommends giving to a manager not thus controlled, a remuneration partly dependent on the profits; which virtually reduces the case to that of a sleeping partner. Or finally, the same person may own the capital, and conduct the business; adding, if he will and can, to the management of his own capital, that of as much more as the owners may be willing to trust him with. But under any or all of these arrangements, the same three things require their remuneration, and must obtain it from the gross profit: abstinence, risk, exertion. And the three parts into which profit may be considered as resolving itself, may be described respectively as interest, insurance, and wages of superintendence.

§2. The lowest rate of profit which can permanently exist, is that which is barely adequate, at the given place and time, to afford an equivalent for the abstinence, risk, and exertion implied in the employment of capital. From the gross profit, has first to be deducted as much as will form a fund sufficient on the average to cover all losses incident to the employment. Next, it must afford such an equivalent to the owner of the capital for forbearing to consume it, as is then and there a sufficient motive to him to persist in his abstinence. How much will be required to form this equivalent depends on the comparative value placed, in the given society, upon the present and the future: (in the words formerly used) on the strength of the effective desire of accumulation. Further, after covering all losses, and remunerating the owner for forbearing to consume,
*94 there must be something left to recompense the labour and skill of the person who devotes his time to the business. This recompense too must be sufficient to enable at least the owners of the larger capitals to receive for their trouble, or to pay to some manager for his, what to them or him will be a sufficient inducement for undergoing it. If the surplus is no more than this, none but large masses of capital will be employed productively; and if it did not even amount to this, capital would be withdrawn from production, and unproductively consumed, until, by an indirect consequence of its diminished amount, to be explained hereafter, the rate of profit was raised.

Such, then, is the minimum of profits: but that minimum is exceedingly variable, and at some times and places extremely low; on account of the great variableness of two out of its three elements. That the rate of necessary remuneration for abstinence, or in other words the effective desire of accumulation, differs widely in different states of society and civilization, has been seen in a former chapter. There is a still wider difference in the element which consists in compensation for risk. I am not now speaking of the differences in point of risk between different employments of capital in the same society, but of the very different degrees of security of property in different states of society. Where, as in many of the governments of Asia, property is in perpetual danger of spoliation from a tyrannical government, or from its rapacious and ill-controlled officers; where to possess or to be suspected of possessing wealth, is to be a mark not only for plunder, but perhaps for personal ill-treatment to extort the disclosure and surrender of hidden valuables; or where, as in the European Middle Ages, the weakness of the government, even when not itself inclined to oppress, leaves its subjects exposed without protection or redress to active spoliation, or audacious withholding of just rights, by any power individual; the rate of profit which persons of average dispositions will require, to make them forego the immediate enjoyment of what they happen to possess, for the purpose of exposing it and themselves to these perils, must be something very considerable. And these contingencies affect those who live on the mere interest of their capital, in common with those who personally engage in production. In a generally secure state of society, the risks which may be attendant on the nature of particular employments seldom fall on the person who lends his capital, if he lends on good security; but in a state of society like that of many parts of Asia, no security (except perhaps the actual pledge of gold or jewels) is good: and the mere possession of a hoard, when known or suspected, exposes it and the possessor to risks, for which scarcely any profit he could expect to obtain would be an equivalent; so that there would be still less accumulation than there is, if a state of insecurity did not also multiply the occasions on which the possession of a treasure may be the means of saving life or averting serious calamities. Those who lend under these wretched governments, do it at the utmost peril of never being paid. In most of the native states of India, the lowest terms on which any one will lend money, even to the government, are such, that if the interest is paid only for a few years, and the principal not at all, the lender is tolerably well indemnified. If the accumulation of principal and compound interest is ultimately compromised at a few shil1ings in the pound, he has generally made an advantageous bargain.

§3. The remuneration of capital in different employments, much more than
*95 the remuneration of labour, varies according to the circumstances which render one employment more attractive, or more repulsive, than another. The profits, for example, of retail trade, in proportion to the capital employed, exceed those of wholesale dealers or manufacturers, for this reason among others, that there is less consideration attached to the employment. The greatest, however, of these differences, is that caused by difference of risk. The profits of a gunpowder manufacturer must be considerably greater than the average, to make up for the peculiar risks to which he and his property are constantly exposed. When, however, as in the case of marine adventure, the peculiar risks are capable of being, and commonly are, commuted for a fixed payment, the premium of insurance takes its regular place among the charges of production, and the compensation which the owner of the ship or cargo receives for that payment, does not appear in the estimate of his profits, but is included in the replacement of his capital.

The portion, too, of the gross profit, which forms the remuneration for the labour and skill of the dealer or producer, is very different in different employments. This is the explanation always given of the extraordinary rate of apothecaries’ profit; the greatest part, as Adam Smith observes, being frequently no more than the reasonable wages of professional attendance; for which, until a late alteration of the law, the apothecary could not demand any remuneration, except in the prices of his drugs. Some occupations require a considerable amount of scientific or technical education, and can [1848] only be carried on by persons who combine with that education a considerable capital. Such is the business of an engineer, both in the original sense of the term, a machine-maker, and in its popular or derivative sense, an undertaker of public works. These are always the most profitable employments. There are cases, again, in which a considerable amount of labour and skill is required to conduct a business necessity of limited extent. In such cases, a higher than common rate of profit is necessary to yield only the common rate of remuneration. “In a small seaport-town,” says Adam Smith, “a little grocer will make forty or fifty per cent upon a stock of a single hundred pounds, while a considerable wholesale merchant in the same place will scarce make eight or ten per cent upon a stock of ten thousand. The trade of the grocer may be necessary for the conveniency of the inhabitants, and the narrowness of the market may not admit the employment of a larger capital in the business. The man, however, must not only live by his trade, but live by it suitably to the qualifications which it requires. Besides possessing a little capital, he must be able to read, write, and account, and must be a tolerable judge, too, of perhaps fifty or sixty different sorts of goods, their prices, qualities, and the markets where they are to be had cheapest. Thirty or forty pounds a year cannot be considered as too great a recompense for the labour of a person so accomplished. Deduct this from the seemingly great profits of his capital, and little more will remain, perhaps, than the ordinary profits of stock. The greater part of the apparent profit is, in this case, too, real wages.”

All the natural monopolies (meaning thereby those which are created by circumstances, and not by law) which produce or aggravate the disparities in the remuneration of different kinds of labour, operate similarly between different employments of capital. If a business can only be advantageously carried on by a large capital, this in most countries limits so narrowly the class of persons who can enter into the employment, that they are enabled to keep their rate of profit above the general level. A trade may also, from the nature of the case, be confined to so few hands, that profits may admit of being kept up by a combination among the dealers. It is well known that even among so numerous a body as the London booksellers, this sort of combination long continued to exist.
*96 I have already mentioned the case of the gas and water companies.

§4. After due allowance is made for these various causes of inequality, namely, differences in the risk or agreeableness of different employments, and natural or artificial monopolies; the rate of profit on capital in all employments tends to an equality. Such is the proposition usually laid down by political economists, and under proper explanations it is true.

That portion of profit which is properly interest, and which forms the real remuneration for abstinence, is strictly the same, at the same time and place, whatever be the employment. The rate of interest, on equally good security, does not vary according to the destination of the principal, though it does vary from time to time very much according to the circumstances of the market. There is no employment in which, in the present state of industry, competition is so active and incessant as in the lending and borrowing of money. All persons in business are occasionally, and most of them constantly, borrowers: while all persons not in business, who possess monied property, are lenders. Between these two great bodies there is a numerous, keen, and intelligent class of middlemen, composed of bankers, stockbrokers, discount brokers, and others, alive to the slightest breath of probable gain. The smallest circumstance, or the most transient impression on the public mind, which tends to an increase or diminution of the demand for loans either at the time or prospectively, operates immediately on the rate of interest: and circumstances in the general state of trade, really tending to cause this difference of demand, are continually occurring, sometimes to such an extent, that the rate of interest on the best mercantile bills has been known to vary in little more than a year (even without the occurrence of the great derangement called a commercial crisis) from four, or less, to eight or nine per cent. But, at the same time and place, the rate of interest is the same, to all who can give equally good security. The market rate of interest is at all times a known and definite thing.

It is far otherwise with gross profit; which, though (as will presently be seen) it does not vary much from employment to employment, varies very greatly from individual to individual, and can scarcely be in any two cases the same. It depends on the knowledge, talents, economy, and energy of the capitalist himself, or of the agents whom he employs; on the accidents of personal connexion; and even on chance. Hardly any two dealers in the same trade, even if their commodities are equally good and equally cheap, carry on their business at the same expense, or turn over their capital in the same time. That equal capitals give equal profits, as a general maxim of trade, would be as false as that equal age or size gives equal bodily strength, or that equal reading or experience gives equal knowledge. The effect depends as much upon twenty other things, as upon the single cause specified.

But though profits thus vary, the parity on the whole, of different modes of employing capital (in the absence of any natural or artificial monopoly) is, in a certain and a very important sense, maintained. On an average (whatever may be the occasional fluctuations) the various employments of capital are on such a footing as to hold out not equal profits, but equal expectations
*97 of profit, to persons of average abilities and advantages. By equal, I mean after making compensation for any inferiority in the agreeableness or safety of an employment. If the case were not so; if there were, evidently, and to common experience, more favourable chances of pecuniary success in one business than in others, more persons would engage their capital in the business, or would bring up their sons to it; which in fact always happens when a business, like that of an engineer at present [1848], or like any newly established and prosperous manufacture, is seen to be a growing and thriving one. If, on the contrary, a business is not considered thriving; if the chances of profit in it are thought to be inferior to those in other employments; capital gradually leaves it, or at least new capital is not attracted to it; and by this change in the distribution of capital between the less profitable and the more profitable employments, a sort of balance is restored. The expectations of profit, therefore, in different employments, cannot long continue very different: they tend to a common average, though they are generally oscillating from one side to the other side of the medium.

This equalizing process, commonly described as the transfer of capital from one employment to another, is not necessarily the onerous, slow, and almost impracticable operation which it is very often represented to be. In the first place, it does not always imply the actual removal of capital already embarked in an employment. In a rapidly progressive state of capital, the adjustment often takes place by means of the new accumulations of each year, which direct themselves in preference towards the more thriving trades. Even when a real transfer of capital is necessary, it is by no means implied that any of those who are engaged in the unprofitable employment relinquish business and break up their establishments. The numerous and multifarious channels of credit, through which, in commercial nations, unemployed capital diffuses itself over the field of employment, flowing over in greater abundance to the lower levels, are the means by which the equalization is accomplished. The process consists in a limitation by one class of dealers or producers, and an extension by the other, of that portion of their business which is carried on with borrowed capital. There is scarcely any dealer or producer on a considerable scale, who confines his business to what can be carried on by his own funds. When trade is good, he not only uses to the utmost his own capital, but employs, in addition, much of the credit which that capital obtains for him. When, either from over-supply or from some slackening in the demand for his commodity, he finds that it sells more slowly or obtains a lower price, he contracts his operations, and does not apply to bankers or other money dealers for a renewal of their advances to the same extent as before. A business which is increasing holds out, on the contrary, a prospect of profitable employment for a larger amount of this floating capital than previously, and those engaged in it become applicants to the money dealers for larger advances, which, from their improving circumstances, they have no difficulty in obtaining. A different distribution of floating capital between two employments has as much effect in restoring their profits to an equilibrium, as if the owners of an equal amount of capital were to abandon the one trade and carry their capital into the other. This easy, and as it were spontaneous, method of accommodating production to demand, is quite sufficient to correct any inequalities arising from the fluctuations of trade, or other causes of ordinary occurrence. In the case of an altogether declining trade, in which it is necessary that the production should be, not occasionally varied, but greatly and permanently diminished, or perhaps stopped altogether, the process of extricating the capital is, no doubt, tardy and difficult, and almost always attended with considerable loss; much of the capital fixed in machinery, buildings, permanent works, &c. being either not applicable to any other purpose, or only applicable after expensive alterations; and time being seldom given for effecting the change in the mode in which it would be effected with least loss, namely, by not replacing the fixed capital as it wears out. There is besides, in totally changing the destination of a capital, so great a sacrifice of established connexion, and of acquired skill and experience, that people are always very slow in resolving upon it, and hardly ever do so until long after a change of fortune has become hopeless. These, however, are distinctly exceptional cases, and even in these the equalization is at last effected. It may also happen that the return to equilibrium is considerably protracted, when, before one inequality has been corrected, another cause of inequality arises; which is said to have been continually the case, during a long series of years, with the production of cotton in the Southern States of North America; the commodity having been upheld at what was virtually a monopoly price, because the increase of demand, from successive improvements in the manufacture, went on with a rapidity so much beyond expectation that for many years the supply never completely overtook it. But it is not often that a succession of disturbing causes, all acting in the same direction, are known to follow one another with hardly any interval. Where there is no monopoly, the profits of a trade are likely to range sometimes above and sometimes below the general level, but tending always to return to it; like the oscillations of the pendulum.

In general, then, although profits are very different to different individuals, and to the same individual in different years, there cannot be much diversity at the same time and place in the average profits of different employments, (other than the standing differences necessary to compensate for difference of attractiveness,) except for short periods, or when some great permanent revulsion has overtaken a particular trade. If any popular impression exists that some trades are more profitable than others, independently of monopoly, or of such rare accidents as have been noticed in regard to the cotton trade, the impression is in all probability fallacious, since if it were shared by those who have greatest means of knowledge and motives to accurate examination, there would take place such an influx of capital as would soon lower the profits to the common level. It is true that, to persons with the same amount of original means, there is more chance of making a large fortune in some employments than in others. But it would be found that in those same employments, bankruptcies also are more frequent, and that the chance of greater success is balanced by a greater probability of complete failure. Very often it is more than balanced: for, as was remarked in another case, the chance of great prizes operates with a greater degree of strength than arithmetic will warrant, in attracting competitors; and I doubt not that the average gains, in a trade in which large fortunes may be made, are lower than in those in which gains are slow, though comparatively sure, and in which nothing is to be ultimately hoped for beyond a competency. The timber trade of Canada is [1848] one example of an employment of capital partaking so much of the nature of a lottery, as to make it an accredited opinion that, taking the adventurers in the aggregate, there is more money lost by the trade than gained by it; in other words, that the average rate of profit is less than nothing. In such points as this, much depends on the characters of nations, according as they partake more or less of the adventurous, or, as it is called when the intention is to blame it, the gambling spirit. This spirit is much stronger in the United States than in Great Britain; and in Great Britain than in any country of the Continent. In some Continental countries the tendency is so much the reverse, that safe and quiet employments probably yield a less average profit to the capital engaged in them, than those which offer greater gains at the price of greater hazards.

It must not however be forgotten, that even in the countries of most active competition, custom also has a considerable share in determining the profits of trade. There is sometimes an idea afloat as to what the profit of an employment should be, which though not adhered to by all the dealers, nor perhaps rigidly by any, still exercises a certain influence over their operations. There has been in England a kind of notion, how widely prevailing I know not, that fifty per cent is a proper and suitable rate of profit in retail transactions: understand, not fifty per cent on the whole capital, but an advance of fifty per cent on the wholesale prices; from which have to be defrayed bad debts, shop rent, the pay of clerks, shopmen, and agents of all descriptions, in short all the expenses of the retail business. If this custom were universal, and strictly adhered to, competition indeed would still operate, but the consumer would not derive any benefit from it, at least as to price; the way in which it would diminish the advantages of those engaged in the retail trade, would be by a greater subdivision of the business. In some parts of the Continent the standard is as high as a hundred per cent. The increase of competition however, in England at least, is rapidly tending to break down customs of this description. In the majority of trades (at least in the great emporia of trade), there are now numerous dealers whose motto is, “small gains and frequent”—a great business at low prices, rather than high prices and few transactions; and by turning over their capital more rapidly, and adding to it by borrowed capital when needed, the dealers often obtain individually higher profits; though they necessarily lower the profits of those among their competitors, who do not adopt the same principle.
*98Nevertheless, competition, as remarked
*99 in a previous chapter, has, as yet, but a limited dominion over retail prices; and consequently the share of the whole produce of land and labour which is absorbed in the remuneration of mere distributors, continues exorbitant; and there is no function in the economy of society which supports a number of persons so disproportioned to the amount of work to be performed.

§5. The preceding remarks have, I hope, sufficiently elucidated what is meant by the common phrase, “the ordinary rate of profit;” and the sense in which, and the limitations under which, this ordinary rate has a real existence. It now remains to consider, what causes determine its amount.

*100To popular apprehension it seems as if the profits of business depended upon prices. A producer or dealer seems to obtain his profits by selling his commodity for more than it cost him. Profit altogether, people are apt to think, is a consequence of purchase and sale. It is only (they suppose) because there are purchasers for a commodity, that the producer of it is able to make any profit. Demand—customers—a market for the commodity, are the cause of the gains of capitalists. It is by the sale of their goods, that they replace their capital, and add to its amount.

This, however, is looking only at the outside surface of the economical machinery of society. In no case, we find, is the mere money which passes from one person to another, the fundamental matter in any economical phenomenon. If we look more narrowly into the operations of the producer, we shall perceive that the money he obtains for his commodity is not the cause of his having a profit, but only the mode in which his profit is paid to him.

The cause of profit is, that labour produces more than is required for its support. The reason why agricultural capital yields a profit, is because human beings can grow more food, than is necessary to feed them while it is being grown, including the time occupied in constructing the tools, and making all other needful preparations: from which it is a consequence, that if a capitalist undertakes to feed the labourers on condition of receiving the produce, he has some of it remaining for himself after replacing his advances. To vary the form of the theorem: the reason why capital yields a profit, is because food, clothing, materials, and tools, last longer than the time which was required to produce them; so that if a capitalist supplies a party of labourers with these things, on condition of receiving all they produce, they will, in addition to reproducing their own necessaries and instruments, have a portion of their time remaining, to work for the capitalist. We thus see that profit arises, not from the incident of exchange, but from the productive power of labour; and the general profit of the country is always what the productive power of labour makes it, whether any exchange takes place or not. If there were no division of employments, there would be no buying or selling, but there would still be profit. If the labourers of the country collectively produce twenty per cent more than their wages, profits will be twenty per cent, whatever prices may or may not be. The accidents of price may for a time make one set of producers get more than the twenty per cent, and another less, the one commodity being rated above its natural value in relation to other commodities, and the other below, until prices have again adjusted themselves; but there will always be just twenty per cent divided among them all.

I proceed, in expansion of the considerations thus briefly indicated, to exhibit more minutely the mode in which the rate of profit is determined.

§6. I assume, throughout, the state of things, which, where the labourers and capitalists are separate classes, prevails, with few exceptions, universally; namely, that the capitalist advances the whole expenses, including the entire remuneration of the labourer. That he should do so, is not a matter of inherent necessity; the labourer might wait until the production is complete, for all that part of his wages which exceeds mere necessaries; and even for the whole, if he has funds in hand, sufficient for his temporary support. But in the latter case, the labourer is to that extent really a capitalist, investing capital in the concern, by supplying a portion of the funds necessary for carrying it on; and even in the former case he may be looked upon in the same light, since, contributing his labour at less than the market price, he may be regarded as lending the difference to his employer, and receiving it back with interest (on whatever principle computed) from the proceeds of the enterprise.

The capitalist, then, may be assumed to make all the advances, and receive all the produce. His profit consists of the excess of the produce above the advances; his
rate of profit is the ratio which that excess bears to the amount advanced. But what do the advances consist of?

It is, for the present, necessary to suppose, that the capitalist does not pay any rent; has not to purchase the use of any appropriated natural agent. This indeed is scarcely ever the exact truth. The agricultural capitalist, except when he is the owner of the soil he cultivates, always, or almost always, pays rent: and even in manufactures, (not to mention ground-rent,) the materials of the manufacture have generally paid rent, in some stage of their production. The nature of rent, however, we have not yet taken into consideration; and it will hereafter appear, that no practical error, on the question we are now examining, is produced by disregarding it.

If, then, leaving rent out of the question, we inquire in what it is that the advances of the capitalist, for purposes of production, consist, we shall find that they consist of wages of labour.

A large portion of the expenditure of every capitalist consists in the direct payment of wages. What does not consist of this, is composed of materials and implements, including buildings. But materials and implements are produced by labour; and as our supposed capitalist is not meant to represent a single employment, but to be a type of the productive industry of the whole country, we may suppose that he makes his own tools, and raises his own materials. He does this by means of previous advances, which, again, consist wholly of wages. If we suppose him to buy the materials and tools instead of producing them, the case is not altered: he then repays to a previous producer the wages which that previous producer has paid. It is true, he repays it to him with a profit; and if he had produced the things himself, he himself must have had that profit, on this part of his outlay, as well as on every other part. The fact, however, remains, that in the whole process of production, beginning with the materials and tools, and ending with the finished product, all the advances have consisted of nothing but wages; except that certain of the capitalists concerned have, for the sake of general convenience, had their share of profit paid to them before the operation was completed. Whatever, of the ultimate product, is not profit, is repayment of wages.

§7. It thus appears that the two elements on which, and which alone, the gains of the capitalists depend, are, first, the magnitude of the produce, in other words, the productive power of labour; and secondly, the proportion of that produce obtained by the labourers themselves; the ratio, which the remuneration of the labourers bears to the amount they produce. These two things form the data for determining the gross amount divided as profit among all the capitalists of the country; but the
rate of profit, the percentage on the capital, depends only on the second of the two elements, the 1abourer’s proportional share, and not on the amount to be shared. If the produce of labour were doubled, and the labourers obtained the same proportional share as before, that is, if their remuneration was also doubled, the capitalists, it is true, would gain twice as much; but as they would also have had to advance twice as much, the rate of their profit would be only the same as before.

We thus arrive at the conclusion of Ricardo and others, that the rate of profits depends on wages; rising as wages fall, and falling as wages rise. In adopting, however, this doctrine, I must insist upon making a most necessary alteration in its wording. Instead of saying that profits depend on wages, let us say (what Ricardo really meant) that they depend on the
cost of labour.

Wages, and the cost of labour; what labour brings in to the labourer, and what it costs to the capitalist; are ideas quite distinct, and which it is of the utmost importance to keep so. For this purpose it is essential not to designate them, as is almost always done, by the same name. Wages, in public discussions, both oral and printed, being looked upon from the point of view of the payers, much oftener than from that of the receivers, nothing is more common than to say that wages are high or low, meaning only that the cost of labour is high or low. The reverse of this would be oftener the truth: the cost of labour is frequently at its highest where wages are lowest. This may arise from two causes. In the first place, the labour, though cheap, may be inefficient. In no European country are wages so low as they are (or at least were
*101) in Ireland: the remuneration of an agricultural labourer in the west of Ireland not being more than half the wages of even the lowest-paid Englishman, the Dorsetshire labourer. But if, from inferior skill and industry, two days’ labour of an Irishman accomplished no more work than an English labourer performed in one, the Irishman’s labour cost as much as the Englishman’s, though it brought in so much less to himself. The capitalist’s profit is determined by the former of these two things, not by the latter. That a difference to this extent really existed in the efficiency of the labour, is proved not only by abundant testimony, but by the fact, that notwithstanding the lowness of wages, profits of capital are not understood to have been higher in Ireland than in England.

The other cause which renders wages, and the cost of labour, no real criteria of one another, is the varying costliness of the articles which the labourer consumes. If these are cheap, wages, in the sense which is of importance to the labourer, may be high, and yet the cost of labour may be low; if dear, the labourer may be wretchedly off, though his labour may cost much to the capitalist. This last is the condition of a country over-peopled in relation to its land; in which, food being dear, the poorness of the labourer’s real reward does not prevent labour from costing much to the purchaser, and low wages and low profits co-exist. The opposite case is exemplified in the United States of America. The labourer there enjoys a greater abundance of comforts than in any other country of the world, except some of the newest colonies; but owing to the cheap price at which these comforts can be obtained (combined with the great efficiency of the labour), the cost of labour to the capitalist is at least not higher, nor the rate of profit lower, than in Europe.
*102

The cost of labour, then, is, in the language of mathematics, a function of three variables: the efficiency of labour; the wages of labour (meaning thereby the real reward of the labourer); and the greater or less cost at which the articles composing that real reward can be produced or procured. It is plain that the cost of labour to the capitalist must be influenced by each of these three circumstances, and by no others. These, therefore, are also the circumstances which determine the rate of profit; and it cannot be in any way affected except through one or other of them. If labour generally became more efficient, without being more highly rewarded; if, without its becoming less efficient, its remuneration fell, no increase taking place in the cost of the articles composing that remuneration; or if those articles became less costly, without the labourer’s obtaining more of them; in any one of these three cases, profits would rise. If, on the contrary, labour became less efficient (as it might do from diminished bodily vigour in the people, destruction of fixed capital, or deteriorated education); or if the labourer obtained a higher remuneration, without any increased cheapness in the things composing it; or if, without his obtaining more, that which he did obtain became more costly; profits, in all these cases, would suffer a diminution. And there is no other combination of circumstances, in which the general rate of profit of a country, in all employments indifferently, can either fall or rise.

The evidence of these propositions can only be stated generally, though, it is hoped, conclusively, in this stage of our subject. It will come out in greater fulness and force when, having taken into consideration the theory of Value and Price, we shall be enabled to exhibit the law of profits in the concrete—in the complex entanglement of circumstances in which it actually works. This can only be done in the ensuing Book. One topic still remains to be discussed in the present one, so far as it admits of being treated independently of considerations of Value; the subject of Rent; to which we now proceed.
