The capitalist tries his best to extract absolute and relative surplus value and to convert it into capital for the exploitation and oppression of the worker on a larger scale. This process of converting surplus value into capital is called capital accumulation. The analysis of capital accumulation makes us realize why in the old society the capitalist who never labored was getting richer and the toiling worker’s lot was getting worse. It helps us further understand why the expropriation of the expropriator, the extinction of capitalism, and the inevitable triumph of socialism cannot be reversed by any reactionary forces and why the overthrow of the evil capitalist system is the great historical mission of the proletariat.
