By most counts, the U.S. economy started growing in the middle of last year. For many Americans, though, it does not feel as if the Great Recession has ended—unemployment and underemployment are still alarmingly high, and job growth is weak. Many causes have been suggested for both the economic collapse and mediocre recovery, but one that is hardly ever mentioned is income inequality. This is a mistake. Growing income inequality in the United States and the policy responses it has spawned have done tremendous damage to our economy. And because we continue to ignore this underlying problem, the risks of our policies leading to another calamity will not go away, no matter what we do to reform the financial sector.
Since 1968, income inequality has been steadily increasing in the United States. I am not referring to the Croesus-like income of a John Paulsen, the hedge fund manager who in 2008 netted over $3 billion, about 75,000 times the average household income. I refer to a more worrying everyday phenomenon that confronts most Americans, the disparity in income growth rates between a manager at the local supermarket and the typical factory worker or office assistant. Since the 1970s, the wages of the former, typically workers at the 90th percentile of the wage distribution in the United States, have grown much faster than the wages of the latter, the typical median worker. Or consider the table below, which shows that the wages of occupation groups that are paid more than the national average in 2002 have grown much faster since then than the wages of occupation groups below the average:

In the present system, the more unrestricted the banks are, the more money they can generate “out of thin air,” and the more damage they can inflict upon the wealth-generation process.
The Banking System Is Still Broken
From the Wall Street Journal:
Borrow from the Federal Reserve at zero and lend to Treasury for a profit. That’s some racket.
Treasury Secretary Tim Geithner and Federal Reserve Chairman Ben Bernanke have announced that the recession is over. Now that the Dow Jones Industrial Average has broken the 10,000 mark, we’ll surely be hearing assurances that economic growth is here to stay. But the credit markets are in much worse shape than some indicators suggest.
