Education will enable young people quickly to familiarize themselves with the whole system of production and to pass from one branch of production to another in response to the needs of society or their own inclinations. It will, therefore, free them from the one-sided character which the present-day division of labor impresses upon every individual. Communist society will, in this way, make it possible for its members to put their comprehensively developed faculties to full use. But, when this happens, classes will necessarily disappear. It follows that society organized on a communist basis is incompatible with the existence of classes on the one hand, and that the very building of such a society provides the means of abolishing class differences on the other.
