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: "Nothing is more calculated to make a demagogue popular than a constantly reiterated demand for heavy taxes on the rich. Capital levies and high income taxes on the larger incomes are extraordinarily popular with the masses, who do not have to pay them." - Socialism
