September 15 will mark the tenth anniversary of the collapse of Lehman Brothers and near meltdown of Wall Street, followed by the Great Recession.

Since hitting bottom in 2009, the economy has grown steadily, the stock market has soared, and corporate profits have ballooned.

But most Americans are still living in the shadow of the Great Recession. More have jobs, to be sure. But they haven’t seen any rise in their wages, adjusted for inflation.

Many are worse off due to the soaring costs of housing, healthcare, and education. And the value of whatever assets they own is less than in 2007.

Last year, about 40 percent of American families struggled to meet at least one basic need – food, health care, housing or utilities, according to an Urban Institute survey.  

All of which suggests we’re careening toward the same sort of crash we had in 2008, and possibly as bad as 1929.

Clear away the financial rubble from those two former crashes and you’d see they both followed upon widening imbalances between the capacity of most people to buy, and what they as workers could produce. Each of these imbalances finally tipped the economy over.

The same imbalance has been growing again. The richest 1 percent of Americans now takes home about 20 percent of total income, and owns over 40 percent of nation’s wealth.

These are nearly the same peaks as in 1928 and 2007. 

The U.S. economy crashes when it becomes too top heavy because the economy depends on consumer spending to keep it going, yet the rich don’t spend nearly as much of their income as the middle class and the poor.

For a time, the middle class and poor can keep the economy going nonetheless by borrowing. But, as in 1929 and 2008, debt bubbles eventually burst.

We’re getting dangerously close. By the first quarter of this year, household debt was at an all-time high of $13.2 trillion.

Almost 80 percent of Americans are now living paycheck to paycheck. In a recent Federal Reserve survey, 40 percent of Americans said they wouldn’t be able to pay their bills if faced with a $400 emergency.
