Whether one agrees or disagrees with the tactics of the Occupy Wall Street movement, it’s easy to understand the inspiration for its anger as well as its impatience.

“Historical movements,” the historian Mary Jo Buhle rightly notes, “are rarely judged solely in the light they cast themselves.” In that sense it is a decidedly risky business to try to draw too many hard and fast conclusions about the present moment in history. Even so, I think the Nobel laureate economist Joseph Stiglitz was as accurate as anyone is likely to be when he pronounced our age—and our government—to be one “of the one percent, by the one percent, for the one percent.”

Think about it: In 1974 the top 0.1 percent of American families enjoyed 2.7 percent of all income in the country. By 2007 this same tiny slice of the population had increased its holdings to fully 12.3 percent—roughly five times as great a piece of the pie as it had enjoyed just three decades earlier. Half the U.S. population owns barely 2 percent of its wealth, putting the United States near Rwanda and Uganda and below such nations as pre-Arab Spring Tunisia and Egypt when measured by degrees of income inequality.

Over one in five American children is living in poverty, and the number is rising. By the end of 2010, corporate profits rose by fully 15 percent of the economic pie—their biggest share of the economy since such statistics became available nearly 70 years earlier—while the share going to workers’ wages dropped to their lowest level in the same period and fell below 50 percent of national income for the first time.

It’s difficult, however, to imagine a time in our politics when our system is so unbalanced in this direction. According to the political scientists Jacob Hacker and Paul Pierson, for instance, the number of political action committees grew from under 300 in 1976 to nearly 5,000 by 2010. The degree of funds these PACs control and direct toward politicians of both parties on issues of concern has the power to overcome almost any group of voters who attempt to organize themselves in opposition....
