"Keynes, it has been stressed, is not a radical. He wanted to reform capitalism in order to make it work better and to preserve it. How is it possible that any capitalist could object to a policy of the preservation of capitalism? The answer is that many capitalists are unaware of the precarious state of the system during a period of serious depression, and do not see the proper relationship between their own position and that of the system as a whole. It is inevitable that most of the effective measures listed in the full-employment legislation above will be strongly opposed by some group of the capitalist population."
