It's good that Milton Friedman is dead, because for the past week Paul Krugman has been trying to kill him off and discredit his monetarist theories.

According to an Aug. 8 post on Krugman's blog at The New York Times, Friedman — whom he designates an "unperson" — has "virtually vanished from the policy discourse."

John Maynard Keynes is back (he never really left), as is Friedrich Hayek, but a few decades from now, historians will regard Friedman as "little more than an economic footnote," the Princeton University economist writes.
