Private Property and Contradiction

According to an alternative to the standard Dialectical Materialist critique of Capitalism, the fundamental concrete Contradiction of the system is located at its foundation--in basic Exchange, involving two parties, each of which seeks to maximize an increase in private property. But, the satisfaction of both goals is impossible, since each consists in getting something for nothing, so the scenario is constituted by a concrete Contradiction. Accordingly, the abolition of private property negates the antagonism, and sublates the interests of each party, thereby accomplishing the transition to Socialism. Perhaps conspicuously absent in this scheme are Class, Class-Consciousness, and Means of Production. However, the Exploitation of Labor can be defined in terms of a simple exchange between a wage-payer and a single worker, and the Socialist goal is Class-lessness that transcends any specific Means of Production. So, those cardinal features of standard Marxism are, nevertheless, only intermediary moments in it.
