Political Philosophy and Drudgery

In his positing of Class Conflict as the motor of History, Marx never quite explains why one class exploits another.  He implicitly seems to believe that such exploitation is a necessary means to the acquisition of wealth, though Nietzsche argues that it is motivated by a Will to Power that is more fundamental then profit-seeking.  However, another explanation is one that is seemingly never addressed in the major works of Political Philosophy, though it is implicit in Marx's hope that technological advances can eliminate the need to exploit Labor.  Conspicuously absent in Plato's cataloguing of what is 'necessary' in a polity is a familiar dimension of every society hitherto known--drudgery, which is not to be confused with the skilled Labor that is the foundation of Marxism.  Accordingly, what Marx and Nietzsche, along with Plato, miss is that power relations are required to ensure that necessary drudgery, e. g. waste disposal, is carried out, since no one voluntarily does so, i. e. requiring if not slavery, at least a class that has no alternative to being consigned to it.  Indeed, the accumulation of wealth can be understood as not for its own sake, but in order to distance oneself from menial work.  Thus, one method of Political Philosophy is to return to Plato's, which has been abandoned by his successors, both Ancient and Modern, and Polbegin with the fundamental premise that the performance of drudgery is necessary, and develop a model on that basis.
