"The dramatic redefinition of state and marketplace over the last two decades demonstrates anew the truth of Keynes' axiom about the overwhelming power of ideas. For concepts and notions that were decidedly outside the mainstream have now moved, with some rapidity, to center stage and are reshaping economies in every corner of the world. Even Keynes himself has been done in by his own dictum. During the bombing of London in World War II, he arranged for a transplanted Austrian economist, Friedrich von Hayek, to be temporarily housed in a college at Cambridge University. It was a generous gesture; after all, Keynes was the leading economist of his time, and Hayek, his rather obscure critic. In the postwar years, Keynes' theories of government management of the economy appeared unassailable. But a half century later, it is Keynes who has been toppled and Hayek, the fierce advocate of free markets, who is preeminent."
