This question is in regards to social philosophy:
Suppose someone is inclined to think that capitalism (at least, the capitalism that is being practiced at present) is neither fair nor egalitarian. In addition, they do not wish to (necessarily) take part in its practice (to make money). My question is this: how could this person expect to make any kind of "decent" money while not being a capitalist when capitalism is (as they say) "the only game in town"?
For a sophisticated discussion of this question--and for a more detailed discussion of several of the issues that Eric raises--see G.A. Cohen's If You're an Egalitarian, How Come You're So Rich? (Harvard University Press, 2000).
