Some people look at income inequality and shrug their shoulders. So what if this person gains and that person loses? What matters, they argue, is not how the pie is divided but the size of the pie. That argument is fundamentally wrong. An economy in which most citizens are doing worse year after year—an economy like America’s—is not likely to do well over the long haul. There are several reasons for this.

First, growing inequality is the flip side of something else: shrinking opportunity. Whenever we diminish equality of opportunity, it means that we are not using some of our most valuable assets—our people—in the most productive way possible. Second, many of the distortions that lead to inequality—such as those associated with monopoly power and preferential tax treatment for special interests—undermine the efficiency of the economy. This new inequality goes on to create new distortions, undermining efficiency even further. To give just one example, far too many of our most talented young people, seeing the astronomical rewards, have gone into finance rather than into fields that would lead to a more productive and healthy economy.
