“Far more important to Smith’s work is the belief that ordinary people normally understand their own interests without help from politicians or professional philosophers.” “The Wealth of Nations is a stupendous palace erected upon the granite of self-interest.”1 So wrote George Stigler, and he represents the majority view over the last two centuries.
