Production Management Systems

Capitalism [is] a system of wage-labour and commodity production for sale, exchange, and profit, rather than for the immediate need of the producers.

Part of the goods which are annually produced, and which are called wealth, is, strictly speaking, waste, because it consists of articles which ... either should not have been produced until other articles had already been produced in sufficient abundance, or should not have been produced at all. And some part of the population is employed in making goods which no man can make with happiness, or indeed without loss of self-respect, because he knows that they had much better not be made; and that his life is wasted in making them.

The product of mental labor — science — always stands far below its value, because the labor-time necessary to reproduce it has no relation at all to the labor-time required for its original production.
