Property relations affording the right of usufruct and despotic control of the workplace to capitalists are the devices by which the surplus value created by workers is appropriated by the capitalists. Capital accumulation: inherent to capitalism is the incessant drive to accumulate as a response to the competitive forces acting upon all capitalists. In such a context the accumulated wealth which is the source of the capitalist's social power derives itself from being able to repeat the circuit of Money→Commodity→Money, where the capitalist receives an increment or "surplus value" higher than their initial investment, as rapidly and efficiently as possible.
