All utopias ... presume too much upon human nature, and therefore must fail. It's very easy for a man to write a book and say, I don't like human nature this way — all right, I'll change it. Karl Marx is one of them. A classless society in which the state withers! We have seen in practice how his followers found it necessary to erect the most despotic state known to history — just to enable those in authority to remain in power. A classless society united in brotherly love and devoted to the public good! Parent-child affection will be replaced by a higher kind of loyalty! Men will work for the love of the state, not for profit! That is where Marx went completely nutty. Any time man plays a trick on Nature, Nature plays a nasty trick in return, and exacts payment with double interest.
