Sad news: Milton Friedman has died
He was truly a revolutionary thinker. People do not realize how revolutionary because so many of his ideas that were thought to be crazy when he suggested them eventually came to be seen as obvious: school choice, a volunteer army, etc.
The least of his accomplishments, but the one that gave me the opportunity to interact with him on a regular basis, was to serve on the Board of Directors of the Becker Center which I direct at the University of Chicago.
Even at the age of 94 he would teach me something about economics whenever we talked.
