I'm just going to make one contribution to this discussion:
YOU MISQUOTED CHURCHILL! Churchill said something very similar to that but it was not about capitalism. It was about democracy.
For the record...
Churchill on Democracy: "Indeed, it has been said that democracy is the worst form of government, except for all the others that have been tried from time to time."
Churchill on Capitalism: "The inherent vice of capitalism is the unequal sharing of blessings; the inherent virtue of socialism is the equal sharing of miseries."
