Some inequality of income and wealth is inevitable, if not necessary. If an economy is to function well, people need incentives to work hard and innovate. The pertinent question is not whether income and wealth inequality is good or bad. It is at what point do these inequalities become so great as to pose a serious threat to our economy, our ideal of equal opportunity and our democracy.
We are near or have already reached that tipping point. It is incumbent on us to dedicate ourselves to reversing this diabolical trend. It will not happen automatically, because the dysfunctions of our economy and politics are not self-correcting when it comes to inequality. In order to reform the system, we need a political movement for shared prosperity. Herewith, a short summary of what has happened, why it has happened, how it threatens the foundations of our society, and what we must do to reverse it.
The data on widening inequality are remarkably and disturbingly clear. The Congressional Budget Office has found that between 1979 and 2007, the onset of the Great Recession, the gap in income—after federal taxes and transfer payments—more than tripled between the top 1 percent of the population and everyone else. The after-tax, after-transfer income of the top 1 percent increased by 275 percent, while it increased less than 40 percent for the middle three quintiles of the population and only 18 percent for the bottom quintile.
The gap has continued to widen in the recovery. According to the Census Bureau, median family and median household incomes have been falling, adjusted for inflation; while according to the data gathered by my colleague Emmanuel Saez, the income of the wealthiest 1 percent has soared by 31 percent. In fact, Saez has calculated that 95 percent of all economic gains since the recovery began have gone to the top 1 percent.
Wealth has become even more concentrated than income. An April 2013 Pew Research Center report found that from 2009 to 2011, “the mean net worth of households in the upper 7 percent of wealth distribution rose by an estimated 28 percent, while the mean net worth of households in the lower 93 percent dropped by 4 percent.”

This trend is now threatening the three foundation stones of our society: our economy, our ideal of equal opportunity and our democracy.
In the United States, consumer spending accounts for approximately 70 percent of economic activity. If consumers don’t have adequate purchasing power, businesses have no incentive to expand or hire additional workers. Because the rich spend a smaller proportion of their incomes than the middle class and the poor, it stands to reason that as a larger and larger share of the nation’s total income goes to the top, consumer demand is dampened. If the middle class is forced to borrow in order to maintain its standard of living, that dampening may come suddenly—when debt bubbles burst.
