Occupy Wall Street protests have spread across the country behind the rallying cry that the “99 percent” have been left behind. There is a sense of outrage that the “system” is not just rigged in favor of the elite – something like the top 1% – but has spun out of control, leading to an accelerating concentration of wealth and power in the hands of the very few.

Wage stagnation, the explosion of health and education costs as the American welfare state shrinks, and above all the financial manipulation of debt has generated extraordinary profits on Wall Street and massive indebtedness and housing foreclosures on Main Street. Losses from outrageous risk-taking by too-big-to-fail financial institutions are made good by the taxpayer, who is told there is no alternative.

This new gilded age political-economic system can be thought of as the interlocking trifecta of a mostly degraded and increasingly dual educational system, a financial system that became mostly unregulated by either law or social norms, and a political system increasingly corrupted by money.

The educational system has promoted a meritocracy of cumulative advantage. The vast majority of American students experience primary and secondary schools during which they fall far behind their peers in much of the rest of the developed (and even less-developed) world, and then face costs of post-secondary education that produce a level of debt that cannot possibly be repaid out of earnings. But the elite reproduces itself with an ability to pay for college and graduate school educations whose superiority has steadily grown, while at the same time feeling entitled since the educational process has also become extraordinarily competitive.

The financial sector was systematically deregulated as free market orthodoxy took off in the 1980s. This deregulation served to extract resources from the “real” economy and concentrated it in the bank accounts of a tiny elite, who are increasingly those same victors of the Darwinian educational competition. As the concentration of income at the very top of the distribution proceeded in the 1990s-2000s, spectacular displays of conspicuous consumption became commonplace. At the same time, a political system corrupted by the absence of meaningful limits to special interest campaign spending could not rein in the financial sector with limits to risk-taking, even after both the magnitude of the crisis and its causes were plain to see.

And in the face of all this, what in the end has been the rallying cry of protest at Occupy Wall Street and beyond? A simple statistic originally generated in a technical article in a leading economics journal by Thomas Piketty and Emmanuel Saez – the after-tax income share of the top 1 percent. Their work told the story of a staggering increase in the share of after-tax income received by those with top incomes since the 1970s. And so: the “99 percent”.

The Congressional Budget Office has just released an update of these figures. The after-tax, after-benefit share of total household income taken by the top 1 percent grew from 8 percent in 1979 to 17 percent in 2007. The shares of each of the bottom four quintiles (together the bottom 80 percent) all fell by 2-3 percentage points. Households in the top quintile but not in the top 1 percent (the 81^st-99^th percentiles) showed no change, while those in the bottom 20 percent fell from 7 percent to 5 percent. In sum, only the top 1% gained, and the top .01 percent gained even more magnificently.

It is not just that wages and salaries have grown vastly more unequal. Policy decisions have greatly reduced the equalizing effect of taxes and transfers. As the CBO puts it, “In 1979, households in the bottom quintile received more than 50 percent of transfer payments. In 2007, similar households received about 35 percent of transfers.”

Our political-economy trifecta (education-finance-politics) has not just rigged the system to syphon the productivity of the economy into the hands of the top 1 percent. It has also systematically attacked the standard of living of workers in the bottom half (or more) of the workforce.

One source of this attack has been to reduce the legal minimum wage to a level so low it has become largely irrelevant as a wage floor. In another post, I will show that different approaches to the use of a statutory minimum wage can go a long way towards explaining why, for over three decades, about 30 percent of all American workers are paid very low wages (less than 2/3 of the median wage). This compares to a 2009 low wage incidence of less than 10 percent of French workers (whose unemployment rate is almost identical!). “30 percent” should become another Metric of Protest.
