"All societies are unequal, but some are more unequal than others." So, "why has the US become more so than just about any other rich country in the past 30 years?" That question is raised by The Atlantic's Matthew O'Brien, in the aftermath of new figures released by the same economists who brought attention to the income gap and gave birth to the occupy movement. Those figures show that America's "1%" took more than a fifth of the nation's income last year — and the top 10% got half – something that's never happened in 100 years of data collection. But 99% have failed to see any boost at all from economic recovery. Is it all about Wall Street and the decline of organized labor? What about access to education and the impact of globalization? Steps used in the past to even the playing field aren't popular any more. Will inequality lead to unrest, or are we all just getting used to it?
