BZZZZT. Ad hominem bullshit.
I didn't see that Will88 was claiming to be a great economist, but he was pointing out (factually or not) that Friedman was wrong about enough things that bending the rules to allow "argument by authority" wouldn't fly in Friedman's case.
Answer the charge about Friedman, and show why his successful predictions are RELEVANT to the issues discussed here. :-)
Cheers!
Which charge? The charge that he knew more about trade than Will88?
