In a piece written for The Nation, Robert Reich argues that the structural reason for today's Great Recession is America's surging inequality:
Consider: in 1928 the richest 1 percent of Americans received 23.9 percent of the nation's total income. After that, the share going to the richest 1 percent steadily declined. New Deal reforms, followed by World War II, the GI Bill and the Great Society expanded the circle of prosperity. By the late 1970s the top 1 percent raked in only 8 to 9 percent of America's total annual income. But after that, inequality began to widen again, and income reconcentrated at the top. By 2007 the richest 1 percent were back to where they were in 1928—with 23.5 percent of the total.
Each of America's two biggest economic crashes occurred in the year immediately following these twin peaks—in 1929 and 2008. This is no mere coincidence. 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 can boost its purchasing power is 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 are continuing their downward slide, and those at the top continue to rake in the lion's share of income. That's why the 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.
The horrible and far reaching fallout of income inequality is thoroughly examined and extremely well documented in The Spirit Level, Why Equality is Better for Everybody, by British epidemiologists Wilkinson and Pickett. It's one of the most illuminating, fascinating books I've read all year. Get your hands on a copy. It's an eye-opener that harnesses the power of scientific research to a very serious social malaise that's damaging us all - rich, poor and everyone in between.
