Still very " scientific " : Karl Marx's labor theory of value

What also would gain popularity in the United States, if more " socialists " bothered to explain it , would be the Marxist labor theory of value. Describing capitalism as system of exploitation and oppression is not just windy rhetoric. This description really does have a scientific basis : One perhaps long forgotten science scholar, J.D. Bernal, writes , writes in his book " Science In History " : [" Marx thus demonstrated that capitalism ,far from being a system of natural justice as the classical economists maintained, was one of extortion imposed by arbitrary force. It was the central concept of EXPLOITATION ,which the economists had hidden from themselves , that was to give the explosive force to Marx's teaching ". .... " It was not that workers and peasants had not felt exploited for centuries, it was rather that now they could understand the mechanism through which the exploitation was carried on ". " The implications of Marxism were so repugnant to the ruling bourgeoisie of the time that it is not surprising that for another fifty years all over the world , and until today in a large part of it , they were ignored and rejected by the official exponents of social science . " ( Bernal's book was first published in Great Britain 1954 )]
