"Wasn't Pinochet the one who brought Friedman's ideas to Chile?"
Pinochet's willingness to listen to Friedman is the only thing that I give him credit for.
Then you don't know enough. Pinochet prevented a civil war or Communist coup, saving tens of thousands (if not hundreds of thousands of lives). And he turned Chile into the freest, most prosperous country in Latin America. Arguably, Pinochet ranks up there as one of the greatest (or the greatest) ruler of any county in the 20th century.
