Part of the hidden complexity that Bert refers to is that Friedman's 
disagreements were with post-war Keynesians, not with Keynes. By the 
time he became engaged with monetary economics and business cycles the 
Keynesian synthesis was well formed. It is interesting that James Tobin, 
for instance, was not mentioned in the PBS show. John Kenneth Galbraith 
is more Goliath-like for viewers than Tobin.
