Wealth can no longer be justified as compensating either labor or the risk of the capitalist. Since the community as a whole produces wealth, the community as a whole must determine its appropriate distribution. In fact, however, they are the material conditions to blow this foundation sky-high. The forces of production would include the organization of labor in the factory system that brings workers together and enables them to discover their identity as a class. Thus, forces of production determine social relations.
Class consciousness can lead to a critical view of the class system as a social relation.
