Wilhelm Röpke (1899–1966) was schooled in the tradition of the Austrians and made enormous contributions to the study of political institutions. His powerful anti-Keynesian writings in particular underscore what an outstanding economist he was and the extent to which he was influenced by Mises. Röpke defended sound money and free trade, and attacked welfare. While some consider him a doubter on free markets, he was in fact a passionate advocate of laissez-faire.
Ludwig von Mises: "The armament industry created militarism and imperialism, however, just as little as, say, the distilleries created alcoholism or publishing houses trashy literature. The supply of weapons did not call forth the demand, but rather the other way around." - Nation, State, and Economy
