I don't like criticizing Milton Friedman not only because he is an old friend but because, outside of monetary theory, we are in complete agreement.

But if I told him what I said before, that I very much doubt whether monetary policy has ever done anything good, he would disagree. He personally is convinced that a good monetary policy is a foundation for everything.
