Rogge, Benjamin A., Can Capitalism Survive? 1979

Benjamin Rogge (1920-1980, Professor at Wabash College, Indiana) collected together his entertaining essays in a volume titled after one of his most famous essays, Can Capitalism Survive? He touches on dozens of topics useful in the classroom and exciting as provocative reading, from the economics of cities (Part VII), to one of his favorites: how to finance education (Part VIII), to the ways in which capitalism and free trade are discussed by the press, politicians, and in the classroom.

Spencer, Herbert The Man Versus The State, with Six Essays on Government, Society, and Freedom. 1992; first published 1884.

Herbert Spencer's collection of essays on sociology, political organization, representative government, and the role of government arrived at the cusp of classical liberal thought. Opposed to both imperialism and socialism (because each ultimately depended on servitude—slavery to an outside force as opposed to individual freedom), Spencer struggled to present his ideas to a world that, during his lifetime, continued inexorably down those very paths.

Six more of his essays on related topics, originally published between 1843 and 1891 in a variety of the many magazines to which Spencer contributed and sometimes served as editor, have been added in subsequent editions, and are available in this Econlib edition.
