The idea that labor exploits capital is equally as plausible, sans assumptions*, as the idea that capital exploits labor. This is only intended as a response to the formal concept, descriptive or normative, of exploitation in Marx's schema from Capital Volume I. * Assumptions include the power relation whereby capital is just assumed to be above labor hierarchically. ~ ~ Capital exploits labor because... ... Capital earns income from production done by labor that capital didn't perform & ~ Labor exploits Capital because... ... Labor earns income from capital that labor didn't buy ~ Basically in good old formal logic fashion both of those cases above, being factual descriptions, are true at once or are false at once.
