LAWRENCE SUMMERS: Friedman, George Stigler, the Chicago School of Economics was very much influenced by Hayek. Certainly Thatcher, and [Anatolii] Chubais in Russia, Vaclav Klaus in the Czech Republic. Hayek has probably the best book expressing the critique of communism as an economic system because it assumed benign motive and still showed how things go wrong, and moved beyond the emphasis on personality Stalin, Mao, and so forth as the source of villainy within communism.
