It is class warfare. But it was begun not by the tear-gassed, rain-soaked protesters asserting their constitutionally guaranteed right of peaceful assembly but rather the financial overlords who control all of the major levers of power in what passes for our democracy. It is they who subverted the American ideal of a nation of stakeholders in control of their economic and political destiny.

Between 1979 and 2007, as the Congressional Budget Office reported this week, the average real income of the top 1 percent grew by an astounding 275 percent. And that is after payment of the taxes that the superrich and their Republican apologists find so onerous.

Those three decades of rampant upper-crust greed unleashed by the Reagan Revolution of the 1980s will be well marked by future historians recording the death of the American dream. In that decisive historical period the middle class began to evaporate and the nation’s income gap increased to alarming proportions. “As a result of that uneven growth,” the CBO explained, “the distribution of after-tax household income in the United States was substantially more unequal in 2007 than in 1979: The share of income accruing to higher-income households increased, whereas the share accruing to other households declined. … The share of after-tax household income for the 1 percent of the population with the highest income more than doubled. …”

That was before the 2008 meltdown that ushered in the massive increase in unemployment and housing foreclosures that further eroded the standard of living of the vast majority of Americans while the superrich rewarded themselves with immense bonuses. To stress the role of the financial industry in this march to greater income inequality as the Occupy Wall Street movement has done is not a matter of ideology or rhetoric, but, as the CBO report details, a matter of discernible fact.

The CBO noted that in comparing top earners, “The [income] share of financial professionals almost doubled from 1979 to 2005” and that “employees in the financial and legal professions made up a larger share of the highest earners than people in those other groups.”

No wonder, since it was the bankers and the lawyers serving them who managed to end the sensible government regulations that contained their greed. The undermining of those regulations began during the Reagan presidency, and so it is not surprising that, as the CBO reports, “the compensation differential between the financial sector and the rest of the economy appears inexplicably large from 1990 onward.” Citing a major study on the subject, the CBO added, “The authors believe that deregulation and corporate finance activities linked to initial public offerings and credit risks are the primary causes of the higher compensation differential.”

So much for the claim that excessive government regulation has discouraged business activity. The CBO report also denies the charge that taxes on the wealthy have placed an undue burden on the economy, documenting that federal revenue sources have become more regressive and that the tax burden on the wealthy has declined since 1979.

In the face of the evidence that class inequality had been rising sharply in the United States even before the banking-induced recession, it would seem that the Occupy Wall Street protests are a quite measured and even timid response to the crisis.

Actually, the rallying cry of that movement was originally enunciated not by the protesters in the streets, but by one of the nation’s most respected economists. Last April, Nobel Laureate Joseph Stiglitz wrote an article in Vanity Fair titled “Of the 1%, by the 1%, for the 1%” that should be required reading for those well-paid pundits who question the logic and motives of the Wall Street protesters. “Americans have been watching protests [abroad] against repressive regimes that concentrate massive wealth in the hands of an elite few,” Stiglitz wrote. “Yet, in our democracy, 1% of the people take nearly a quarter of the nation’s income—an inequality even the wealthy will come to regret.”

Maybe justice will prevail despite the suffering that the 1 percent has inflicted on the foreclosed and the jobless. But to date those who have seized 40 percent of the nation’s wealth still control the big guns in this war of classes.
