Has America Become an Oligarchy?

Hacker and Pierson are far from the only economists and political scientists to recognize a fundamental societal distortion. Larry Bartels, one of America's leading political scientists, also believes America has entered a new Gilded Age. Bartels' 2008 book on the subject, "Unequal Democracy: The Political Economy of the New Gilded Age," has drawn a great deal of attention and even been quoted by President Barack Obama.

"The really dramatic economic gains over the past 30 years have been concentrated among the extremely rich," Bartels writes, "largely bypassing even the vast majority of ordinary rich people in the top 5 percent of income distribution." He doesn't see this fundamental shift in the distribution of wealth as having resulted from market forces or drastic events, such as the financial crisis. Instead, he believes they are "the result of policy choices."

As Bartels explains, much as the economic giants of the Gilded Age developed such enormous influence that they could dictate basic political conditions, today's Wall Street bosses and CEOs have successfully arranged extensive deregulation for their industries. Indeed, he argues that this is the only thing that can explain how hedge fund managers suddenly started making billions of dollars a year. Former Citigroup CEO Sanford Weill, for example, kept a framed pen in his office as a symbol of his influence. It was the pen President Bill Clinton -- at Weill's instigation -- used in 1999 to sign into law legislation repealing the provisions in the Glass-Steagall Act of 1933 that separated the transactions of investment and commercial banks.

At the same time, Bartels writes, the wealthy receive enormous tax breaks worth hundreds of billions of dollars. In the 1970s, capital gains tax was 40 percent, and the highest income tax bracket paid a rate of 70 percent. Under George W. Bush, these rates dropped to 15 percent and 35 percent, respectively. For example, it emerged a few weeks ago that legendary investor Warren Buffett earned $63 million last year but was only required to pay 17 percent in taxes.

The question is: How long can the US withstand this internal tension?

Differences between rich and poor are tolerated as long as the rags-to-riches story of the dishwasher-turned-millionaire remains theoretically possible. But studies show that increasing inequality and political control concentrated in the hands of the wealthy elite have drastically reduced economic mobility and that the US has long since fallen far behind Europe on this issue. Indeed, only 4 percent of less-well-off Americans ever successfully make the leap into the upper-middle class.

"The major difference between this Gilded Age and the last one is the relative absence of protest," historian Gary Gerstle told the online magazine Salon in October. "In the first Gilded Age, the streets were flooded with protest movements."

Manhattan hasn't yet quite reached that point.
