Interestingly enough the issues you list seem related to capitalism rather than just any form of societal system.

Many literary utopias have non-capitalist systems but usually some sort of circular sharing system (some are outright communist, but others more slow living).

Greed must always be checked by a society. But since Calvinism we've had a dual moral reasoning (was that Charles Taylor or Hegel, can't recall). Through Calvinism capitalism attained the moral good of earning more than you need, to deploy greed for God.

Humans are naturally greedy (natural egoism is not immoral just a biological drive) and our political system should balance that out somehow.
