So now the wingnuts want a specific source for quotes, interesting as I have tried to confirm quotes from you winguts with no luck. Having read Keynes, the quote is consistent with his thinking and a few quotes with sources are below. Since you birdbrains get your thoughts from corporate big money, I find it ironic you'd question another with no proof. Do you tools proof your corporate brain?
But since I add my own thoughts, no need to question the quote, question me and I will confirm your stupidity. That's easy. If Keynes didn't say it, fine, it still fits and I'll attach my name to it anytime.
"To suggest social action for the public good to the City of London is like discussing the Origin of Species with a bishop sixty years ago. The first reaction is not intellectual, but moral. An orthodoxy is in question, and the more persuasive the arguments the graver the offence." John Maynard Keynes

"Material poverty provides the incentive to change precisely in situations where there is very little margin for experiments. Material prosperity removes the incentive just when it might be safe to take a chance. Europe lacks the means, America the will, to make a move. We need a new set of convictions which spring naturally from candid examination of our own inner feelings in relation to the outside facts." John Maynard Keynes
PS because a quote appears after an author's death is a meaningless argument. I often take pieces from Tony Judt and he too is sadly gone. You people are fools plain and simple.
Later edit:
"I do not know which makes a man more conservative — to know nothing but the present, or nothing but the past." LOL I am not home in Philly today so I can't pull my Keynes off the shelf for fun to quote, but I do have the PDF with the this quote on my PC. And to add to my comment above, one, to be honest would need to search all references to Keynes to disprove the quote. Do you know that it was not quoted in a biography or opinion piece from friend or even foe. Carry on conservatives, oh I mean whine on, you guys do that so well.
