This moderated (by an economist) dialog between Milton Friedman and Walter Heller is wonderful in hi-lighting differences and simularities between a Libertarian economist like Friedman and a more mainstream economist, Walter Heller, who would identify more closely with Keynes. (and for jem, here is another use of the term "fine tuning")
I compare those guys to the political hacks we see today being called experts. I can listen to those guys all day long. Today's expert class is so annoying and so poltical. Every sentence out of their mouth is rehearsed politics. I can't watch. Here we see hayek really thinking and answering questions and realizing he needed to explain Keynes was really smart in many areas... just not that deep on economic theory of others. thanks for that piezoe.
