 Note that the claim that the capitalist appropriates part of the value of the worker’s product (step 4) is not (as it stands) a normative one. For that appropriation to constitute wrongful exploitation the normative dimensions of the step from 4 to 5 in the Plain Argument would need to be fleshed out. The present section outlines three candidate explanations of the relevant wrongfulness—involving the ideas of unfairness, instrumentalising vulnerability, and domination, respectively—which have found support within analytical Marxism.
