I guess the problem I have with terms like "justice" and "injustice" (not to pick on you specifically) is it seems to presume that poverty is the result of greed or nefarious motives when it's exclusively the result of economic inefficiency (sometimes this inefficiency is caused by greed). In failing to properly diagnose the problem, solutions come out which actually reduce market efficiency and thus perpetuate more poverty. Moreover, everyone already agrees that poverty is bad, so arguing about "injustice" instead of "optimizing the economy" seems unlikely to persuade anyone.

I'm already on board with eliminating poverty! Don't tell me "hiking the minimum wage is the right thing to do and the economics will work itself out", show me the math that says we can do it without inadvertently creating more poverty.
