I agree Tony. Keynes was smarter than his present day critics.
JFK shrewdly used Keynsian economics to grow the US economy in the early 1960s. His investments (NASA, highways etc) produced the highest US standard of living, before or since.
It's been downhill since Nov 22, 1963.
Unfortunately, Keynes' advice was ignored by the Americans at Breton Woods after WW II.
