" Hopes Betrayed" establishes Keynes` historical setting and explains what turned him into a radical economist. He gives an analysis of the economist`s sustained assault on conventional wisdom, and shows how Keynes` story is not just that of a revolution in economic theory, but also part of the story of the evolution of modern government. Other books by Robert Skidelsky include " Politicians and the Slump" , " The End of the Keynesian Era" and " Oswald Mosley" .
