Can't it be "poor people are getting poorer because rich people are taking wealth away from them on balance, and that makes us mad". I mean... that's bad right? It should make us mad. We're a wealthier society on average than we were in the 80's, we all should be wealthier, yet we aren't.

I genuinely don't understand the denialism on this. You don't have to be a raving socialist to recognize that an outcome is unfair. Can't you be a free market republican and want to see the poor do better along with the rest of us?
