If Keynes was the most influential economist of the first half of the 20th century, then Milton Friedman was the most influential economist of the second half . . . Any honest Democrat will admit that we are now all Friedmanites . . . I grew up in a family of progressive economists, and Milton Friedman was a devil figure. But over time, as I studied economics myself and as the world evolved, I came to have grudging respect and then great admiration for him and his ideas . . . Today we take it as given that free financial markets shape finance . . . At the time Mr. Friedman first proposed flexible exchange rates and open financial markets, it was thought that they would be inherently destabilizing.
