Milton Friedman

Friedman is the pragmatist of the tradition: Capitalism and Freedom (1962) argued that economic freedom protects political freedom, then proposed workable fixes rather than abolition, including school vouchers, a negative income tax in place of welfare bureaucracy and an end to military conscription, which came in 1973. Purists objected that vouchers and income guarantees keep the state funding everything; supporters reply that his ideas actually became policy.
