Between 1989 and 2010, the top 1 percent of the population went from holding 30.1 percent of the wealth to 34.5 percent, while the bottom 50 percent went from having 3 percent of the wealth to having just 1.1 percent. That's right: In 2010, 50 percent of Americans had 1.1 percent of the total net worth
(PDF), according to the Congressional Research Service. The share of wealth held by the next 40 percent of people, up to the 90th percentile, had also dropped, from 29.9 percent to 24.3 percent. Put another way (and it's stunning however you look at it), 10 percent of people have 74.5 percent of the wealth.
The median and mean household net worth dropped considerably between 2007 and 2010, but even as both dropped, inequality increased, with the median—the amount of wealth that half of people have more than and half of people have less than—dropping by 38.8 percent, while the mean—the amount you get when you add up all the wealth and divide it by the number of people—lost just 14.4 percent. That means that the amount everyone would have if wealth were distributed equally went from being 4.6 times the amount the person actually in the middle has to being 6.5 times that number.
So: Prior to the financial crisis and the recession, there was massive inequality in America. Following the financial crisis and the recession, there is a Grand Canyon of inequality in America. For good reason, we talk a lot about how much of the wealth the top 1 percent have. We talk less about how little the bottom 50 percent have, but think about what it means that 50 percent of people have just over 1 percent of the money. Forget all the definitions you've heard of who is in the underclass. We're on track to have "underclass" and "majority" be synonyms. And the Republicans have got a guy running for president who wants to speed the process.
