This is exactly what Mitt Romney was referring to during the 2012 election when he said he wasn't worried about the very rich, and he wasn't worried about the very poor. The truth is if you are making $20k/yr in income you're likely in a better position day-to-day than someone making $40k/yr, especially if you're raising a family and especially if you live in a city with functioning social services. He was excoriated in the press for saying he didn't care about poor people, which isn't exactly what he said and isn't at all what he meant.
