My younger brother is an Economics genius.... 99.45 ATAR last year with something like 3rd in the state for Economics (with a shit teach might I add)...
He said he'd read both of those... and that yes Friedman is a nutcase... but he also described Murray Rothbard's principles as economically unsound and slightly on the side of economic theory not practically... and by slightly he meant a lot... mainly in that he believes that Rothbard has no clue what it is to live like in a poorer situation...
And while I do actually believe you know something about what you're talking about man, my brother is a genius when it comes to this stuff (for his graduation present my parentals organised a meet with the Governer of the Reserve Bank and he held his own and from what I understand he convinced him of a new school viewpoint that he was skeptical about... so I'm going to go with his word on this
