Contributive Justice and Communism

Probably the only two prominent examples of Contributive Justice being entailed in a Political Philosophy are from Plato and Marx.  In both cases it is the concept of each member of a society doing what they do well, the difference being that the former, but not the latter, distinguishes those abilities by natural classes.  Regardless, they share a communist vision of the best society.  Under such conditions, doing one's fair share is not regarded as an imposition, but as a pleasure, just as it is in any collective enterprise.  Conversely, therefore, the rarity of Contributive Justice as a principle in the history of Political Philosophy is a reflection of the predominance of Atomism, even in the case of Aristotle, whose pronounced Holism is inconsistent, as has been previously discussed.
