The facts don’t comport with the outcomes predicted by Friedman’s theories.
That means he was wrong.
It isn’t how much any of us “knows” vs. Friedman. It’s the facts as they exist today that prove him wrong, much as the stabilizing temperatures around the world for the last 14+ years are rapidly disproving the AGW hysterics’ theories.
Reality trumps theory. Or, to quote Yogi Berra: “The difference between theory and reality is that in theory, there’s no difference.”
