Robert Reich is right: No one ever mentions this on the teevee. (Instead, we have people like Mrs. Alan Greenspan and Mika Brzezinski giving us stern lectures about tightening our belts.) In real dollars, adjusted for inflation, people are actually making less than they made thirty years ago. This is a massive systemic problem and it will require a major course correction to fix (and no, I don't mean cutting unemployment benefits):

Missing from almost all discussion of America’s dizzying rate of unemployment is the brute fact that hourly wages of people with jobs have been dropping, adjusted for inflation. Average weekly earnings rose a bit this spring only because the typical worker put in more hours, but June’s decline in average hours pushed weekly paychecks down at an annualized rate of 4.5 percent.

In other words, Americans are keeping their jobs or finding new ones only by accepting lower wages.

Meanwhile, a much smaller group of Americans’ earnings are back in the stratosphere: Wall Street traders and executives, hedge-fund and private-equity fund managers, and top corporate executives. As hiring has picked up on the Street, fat salaries are reappearing. Richard Stein, president of Global Sage, an executive search firm, tells the New York Times corporate clients have offered compensation packages of more than $1 million annually to a dozen candidates in just the last few weeks.

We’re back to the same ominous trend as before the Great Recession: a larger and larger share of total income going to the very top while the vast middle class continues to lose ground.

And as long as this trend continues, we can’t get out of the shadow of the Great Recession. When most of the gains from economic growth go to a small sliver of Americans at the top, the rest don’t have enough purchasing power to buy what the economy is capable of producing.

America’s median wage, adjusted for inflation, has barely budged for decades. Between 2000 and 2007 it actually dropped. Under these circumstances the only way the middle class could boost its purchasing power was to borrow, as it did with gusto. As housing prices rose, Americans turned their homes into ATMs. But such borrowing has its limits. When the debt bubble finally burst, vast numbers of people couldn’t pay their bills, and banks couldn’t collect.

A second parallel links 1929 with 2008: when earnings accumulate at the top, people at the top invest their wealth in whatever assets seem most likely to attract other big investors. This causes the prices of certain assets—commodities, stocks, dot-coms or real estate—to become wildly inflated. Such speculative bubbles eventually burst, leaving behind mountains of near-worthless collateral.

The crash of 2008 didn’t turn into another Great Depression because the government learned the importance of flooding the market with cash, thereby temporarily rescuing some stranded consumers and most big bankers. But the financial rescue didn’t change the economy’s underlying structure — median wages dropping while those at the top are raking in the lion’s share of income.

That’s why America’s middle class still doesn’t have the purchasing power it needs to reboot the economy, and why the so-called recovery will be so tepid—maybe even leading to a double dip. It’s also why America will be vulnerable to even larger speculative booms and deeper busts in the years to come.
