This paper argues that exploitation is a central and non-redundant concept in a Marxian understanding of capitalism. This finding runs counter to John Roemer’s conclusion in his critical reexamination of exploitation. For a static setting with perfectly competitive markets, Roemer shows that exploitation is a property of agents which derives from unequal wealth endowments, that is, from differential ownership of productive assets, not a social relation between capitalists and workers. Further, he shows that DOPA suffices in this setting to generate (...) core phenomena in Marxian theory-accumulation, domination, alienation, and inequality-with no reference to an independent notion of exploitation. Roemer concludes that DOPA is the central analytical category in Marxian theory, and exploitation a redundant, indeed incorrect, concept therein. A direct implication is that distributive justice should be Marxism’s central ethical concern. The basis for Roemer’s sweeping conclusion is that his model is general, incorporating no special institutional assumptions and abstracting from any impediments to market equilibria. That is, his conclusion rests on an ahistorical, timeless economic model. (shrink)
