When I was a young man, I felt attracted to the Young Marx's idea of alienation. His idea of a communist society sounds a lot like libertarian one: where freed from the drudgery of material compulsion, people would find their own happiness in pursuing their own talents. Some would fish and others would paint. The point is man would not be acted by an outside force against himself; man would be the master of his own nature and the agent of his own well-being. Sounds idyllic doesn't it? The flaw in the theory as attractive as it sounds, is that if getting rid of alienation would make men happy, it would already happen and no force would be required to liberate human beings from the bonds that keep them from connecting to their real selves. And there is no evidence any communist society has managed to make people happy by freeing them of wants and renewing their once-lost freedom and authentic state of being.
Yes. So they must be controlled until They can bring about the proper order of things.
