Steps must be taken to preserve middle-class America or the United States will cease to be a democracy, says Vanderbilt law professor Ganesh Sitaraman, author of the new book, The Crisis of the Middle-Class Constitution: Why Economic Inequality Threatens Our Republic.

The shrinking middle class is a constitutional problem because our Constitution wasn’t designed for a country with significant economic inequality,” says Sitaraman.

The problem of economic inequality is not new, Sitaraman says.

“From the time of the ancients, statesmen and philosophers were deeply worried about the problem of economic inequality,” he says. “They worried that either the rich would oppress the poor or the poor would seek to confiscate the wealth of the rich, and the result would be violence, instability, even revolution.” Throughout history, Sitaraman says, governments used various methods to create stability, such as having bodies of government representing different economic classes.

The United States, Sitaraman argues, does not have any of these features because the founding era was relatively equal economically. With no feudalism, no hereditary aristocracy, and vast lands to the West, the founders built the Constitution on the basis of relative economic equality. The problem today, Sitaraman argues, is that there is a growing gulf between the affluent and everybody else.

Steps such as raising the minimum age, investing more in education, making voting more convenient and campaign finance reform would help, he says.

If the issue isn’t addressed, the middle class will continue to shrink and Sitaraman believes the United States will cease to exist as a democracy.

“You’d end up with an oligarchy or revolution and mob rule, and both of those things were not what the founders wanted when they were trying to create a representative democracy in America,” he says.

Ganesh Sitaraman is an associate professor of law at Vanderbilt Law School and a senior fellow at the Center for American Progress. From 2011 to 2013, he served as policy director to Sen. Elizabeth Warren, D-Mass., during her successful Senate campaign, and then as her senior counsel in the Senate.
