In a plutonomy, Kapur and his co-authors wrote, “economic growth is powered by and largely consumed by the wealthy few.” America had been in this state twice before, they noted—during the Gilded Age and the Roaring Twenties. In each case, the concentration of wealth was the result of rapid technological change, global integration, laissez-faire government policy, and “creative financial innovation.” In 2005, the rich were nearing the heights they’d reached in those previous eras, and Citigroup saw no good reason to think that, this time around, they wouldn’t keep on climbing. “The earth is being held up by the muscular arms of its entrepreneur-plutocrats,” the report said. The “great complexity” of a global economy in rapid transformation would be “exploited best by the rich and educated” of our time.

Kapur and his co-authors were wrong in some of their specific predictions about the plutonomy’s ramifications—they argued, for instance, that since spending was dominated by the rich, and since the rich had very healthy balance sheets, the odds of a stock-market downturn were slight, despite the rising indebtedness of the “average” U.S. consumer. And their division of America into only two classes is ultimately too simple. Nonetheless, their overall characterization of the economy remains resonant. According to Gallup, from May 2009 to May 2011, daily consumer spending rose by 16 percent among Americans earning more than $90,000 a year; among all other Americans, spending was completely flat. The consumer recovery, such as it is, appears to be driven by the affluent, not by the masses. Three years after the crash of 2008, the rich and well educated are putting the recession behind them. The rest of America is stuck in neutral or reverse.

Income inequality usually shrinks during a recession, but in the Great Recession, it didn’t. From 2007 to 2009, the most-recent years for which data are available, it widened a little. The top 1 percent of earners did see their incomes drop more than those of other Americans in 2008. But that fall was due almost entirely to the stock-market crash, and with it a 50 percent reduction in realized capital gains. Excluding capital gains, top earners saw their share of national income rise even in 2008. And in any case, the stock market has since rallied. Corporate profits have marched smartly upward, quarter after quarter, since the beginning of 2009.

Even in the financial sector, high earners have come back strong. In 2009, the country’s top 25 hedge-fund managers earned $25 billion among them—more than they had made in 2007, before the crash. And while the crisis may have begun with mass layoffs on Wall Street, the financial industry has remained well shielded compared with other sectors; from the first quarter of 2007 to the first quarter of 2010, finance shed 8 percent of its jobs, compared with 27 percent in construction and 17 percent in manufacturing. Throughout the recession, the unemployment rate in finance and insurance has been substantially below that of the nation overall.
