Okay then, fine... suppose that the family of five was given the purchasing power for a house through higher wages, paid for by the same amount taken through pay cuts on the rich. Same deal.
If the companies won't do it themselves, then the government has to step in and establish floors (minimum wage) and ceilings (massive taxes at higher tax brackets.) Our current floors and ceilings are very far apart, which creates massive economic growth at the cost of social equality, and increases average income at a faster rate than more socialist nations like Denmark.
Still, the average Dane is happier even if the average American is wealthier. So that should tell you what our nation's economic priorities are.
