Then came the concentration of the means of production and of the producers in large workshops and manufactories, their transformation into actual socialized means of production and socialized producers. But the socialized producers and means of production and their products were still treated, after this change, just as they had been before, _i.e._, as the means of production and the products of individuals. Hitherto, the owner of the instruments of labor had himself appropriated the product, because, as a rule, it was his own product and the assistance of others was the exception. Now the owner of the instruments of labor always appropriated to himself the product, although it was no longer _his_ product but exclusively the product of the _labor of others_. Thus, the products now produced socially were not appropriated by those who had actually set in motion the means of production and actually produced the commodities, but by the _capitalists_. The means of production, and production itself, had become in essence socialized. But they were subjected to a form of appropriation which presupposes the private production of individuals, under which, therefore, every one owns his own product and brings it to market. The mode of production is subjected to this form of appropriation, although it abolishes the conditions upon which the latter rests.[4] This contradiction, which gives to the new mode of production its capitalistic character, _contains the germ of the whole of the social antagonisms of to-day_. The greater the mastery obtained by the new mode of production over all important fields of production and in all manufacturing countries, the more it reduced individual production to an insignificant residuum, _the more clearly was brought out the incompatibility of socialized production with capitalistic appropriation_.
