The Census Bureau just released its latest report on income and poverty in America and this is the picture that it painted:
Then, there's median incomes:
Finally, there's a part of this report that is seldom revealed because it doesn't fit the liberal view in America that the rich get richer while the poor get poorer. In 2013, 30.9% of those who were in poverty from the period of 2007 to 2013 (just 5 years), elevated themselves out of poverty. At the same time, 32.2% of those who were in the top 20% of incomes fell out of that top spot. This is consistent with the fact that, in this country, most people rise out of poverty in just 10 years and, similarly, most rich lose much of their wealth in a similar amount of time. This income mobility for the poor is a real form of positive income redistribution that rarely occurs in any other county. At the same time, the fact that 32.2% of the richest drop in wealth in just five years definitely refutes the long-time progressive argument that the rich only get richer.
