The shift in wealth and income in America is not as great as I had thought, but it's significant. I like graphs, so here's one from the study:

Government policies are very important. Both Republicans and Democrats understand this. Republicans like the general slope of the curve since Reagan began favoring the rich. They plan to fight to keep it moving in a direction that favors the rich. I don't think this is good for America. It makes America different from the country that I grew up in during the 1960s and 70s. I still believe that part of the goodness of America during that period was that all members of the "Greatest Generation," rich and poor, had fought together in World War II, which had imposed some self-restraint on the greed of the leaders of the country, a restraint that does not exist today. Significantly, Reagan, although he served in the military during WW II, did not fight; he just continued to make movies in California, albeit for the military while in uniform. George H.W. Bush was a much better representative of the Greatest Generation than Reagan was.
The fight over where we go from here may lead to a government shutdown. But from the looks of this graph, the last shutdown did not have much effect.
