Once upon a time, the American economy worked. The new, harsh reality is that the bottom 90 percent of households are poorer today than they were in 1987 -- it turns out that everybody but the richest 10 percent of Americans are worst off. That includes the poor, the entire middle class, and even what we would consider much of the upper class. In this chart, I've taken each group's inflation-adjusted net worth from 1945 and indexed that to 100, so we can compare how wealth has grown for people with lots or little of it. It's been a lost 25 years for the bottom 90 percent, but a lost 15 for the next 9 percent, too. That's right: altogether, the bottom 99 percent are worth less today than they were in 1998. But this isn't a story about the top 1 percent running away from everybody else. It's a story about the top 0.1 - scratch that, the top 0.01 percent - doing so. Indeed, since 1980, the top 0.01 percent's piece of the wealth pie has increased by 8.6 percentage points, while the next 0.09 percent's has done so by 5.4. The bottom 99 percent, meanwhile, have seen their wealth share fall an astonishing 18 percentage points.
