Nicholas Kristof in the New York Times:
The frustration in America isn’t so much with inequality in the political and legal worlds, as it was in Arab countries, although those are concerns too. Here the critical issue is economic inequity. According to the C.I.A.’s own ranking of countries by income inequality, the United States is more unequal a society than either Tunisia or Egypt.
Three factoids underscore that inequality:
…¶The 400 wealthiest Americans have a greater combined net worth than the bottom 150 million Americans.
…¶The top 1 percent of Americans possess more wealth than the entire bottom 90 percent.
…¶In the Bush expansion from 2002 to 2007, 65 percent of economic gains went to the richest 1 percent.
