Abstract
G. A. Cohen and John Roemer, two of the most influential of the ‘Analytic Marxists,’ have argued convincingly that the Marxian concept of exploitation must include injustice as part of its definition. ‘Exploitation’ is more like ‘murder’ which includes injustice in its very meaning, than like ‘killing’ which describes a fact which is often unjust but need not be. ‘Forced extraction of unpaid or surplus labor,’ then, is not sufficient for exploitation. The extraction must be unjust to be exploitative. Otherwise we would have to call it exploitation if people were forced to labor without pay as just punishment, or if people-selected by lottery-were drafted to fight a defensive war and provided no more than subsistence for their trouble, or if initiators of an unjust war were forced to labor to repair the damages they had caused.
