From a post by Robert Reich on his blog:
The economy won’t really bounce back until America’s surge toward inequality is reversed. Even if by some miracle President Obama gets support for a second big stimulus while Ben S. Bernanke’s Fed keeps interest rates near zero, neither will do the trick without a middle class capable of spending. Pump-priming works only when a well contains enough water.I don't see much hope for America. There should be political revolts against the current downward trend. Instead, the ultra-rich have cleverly used the media to build astro-turf groups to agitate for pro-ultra-rich policies, more tax cuts, more deregulation, more anti-worker laws, the destruction of social safety nets, etc.
Look back over the last hundred years and you’ll see the pattern. During periods when the very rich took home a much smaller proportion of total income — as in the Great Prosperity between 1947 and 1977 — the nation as a whole grew faster and median wages surged. We created a virtuous cycle in which an ever growing middle class had the ability to consume more goods and services, which created more and better jobs, thereby stoking demand. The rising tide did in fact lift all boats.
During periods when the very rich took home a larger proportion — as between 1918 and 1933, and in the Great Regression from 1981 to the present day — growth slowed, median wages stagnated and we suffered giant downturns. It’s no mere coincidence that over the last century the top earners’ share of the nation’s total income peaked in 1928 and 2007 — the two years just preceding the biggest downturns.
Starting in the late 1970s, the middle class began to weaken. Although productivity continued to grow and the economy continued to expand, wages began flattening in the 1970s because new technologies — container ships, satellite communications, eventually computers and the Internet — started to undermine any American job that could be automated or done more cheaply abroad. The same technologies bestowed ever larger rewards on people who could use them to innovate and solve problems. Some were product entrepreneurs; a growing number were financial entrepreneurs. The pay of graduates of prestigious colleges and M.B.A. programs — the “talent” who reached the pinnacles of power in executive suites and on Wall Street — soared.
The middle class nonetheless continued to spend, at first enabled by the flow of women into the work force. (In the 1960s only 12 percent of married women with young children were working for pay; by the late 1990s, 55 percent were.) When that way of life stopped generating enough income, Americans went deeper into debt. From the late 1990s to 2007, the typical household debt grew by a third. As long as housing values continued to rise it seemed a painless way to get additional money.
Eventually, of course, the bubble burst. That ended the middle class’s remarkable ability to keep spending in the face of near stagnant wages. The puzzle is why so little has been done in the last 40 years to help deal with the subversion of the economic power of the middle class.
