Likewise, in considering the gross output of capitalist production in an economy as a whole, Marx divides its value into these four components. He argues that the total new value added in production, which he calls the value product, consists of the equivalent of variable capital, plus surplus value. Thus, the workers produce by their labor both a new value equal to their own wages, plus an additional new value which is claimed by capitalists by virtue of their ownership and supply of productive capital.
