What the **** are you talking about? You think Milton Friedman was a central planner witch doctor?
He worked with and enabled some of the greatest authoritarian economic witch doctors of all time, including FDR....In fact one of Friedman's greatest regrets is that he foisted income tax withholding upon the nation.
Unlike some, I don't consider Friedman to be an economic demi-god.
Friedman was a lead in the Chicago boys economics. Think south America...Pinochet, anyone. In other words, yes, Friedman was for central planning in monetary policy. Keynes was too. He himself said his theories would work best under authoritarian style governments. Shocker, he was right.
What most all modern day economists have in common is they believe in the control/plan model of economics. There is a concensus that economics is a hard science, when it is not. In order to prove their a priori values correct in mathematics, they must eventually succumb to controlling it all.
Economics is a human action and can not be quantified in natural science. Monetarists have some things right, but fall right into the planning trap.
