In a fantastic piece for Vanity Fair, acclaimed economist Joseph Stiglitz discusses what America’s vast income inequality means for our future — in short, how it will corrode and distort every aspect of society:
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.
Third, and perhaps most important, a modern economy requires “collective action”—it needs government to invest in infrastructure, education, and technology. The United States and the world have benefited greatly from government-sponsored research that led to the Internet, to advances in public health, and so on. But America has long suffered from an under-investment in infrastructure (look at the condition of our highways and bridges, our railroads and airports), in basic research, and in education at all levels. Further cutbacks in these areas lie ahead.
America’s inequality distorts our society in every conceivable way. There is, for one thing, a well-documented lifestyle effect—people outside the top 1 percent increasingly live beyond their means. Trickle-down economics may be a chimera, but trickle-down behaviorism is very real. Inequality massively distorts our foreign policy. The top 1 percent rarely serve in the military—the reality is that the “all-volunteer” army does not pay enough to attract their sons and daughters, and patriotism goes only so far. Plus, the wealthiest class feels no pinch from higher taxes when the nation goes to war: borrowed money will pay for all that. Foreign policy, by definition, is about the balancing of national interests and national resources. With the top 1 percent in charge, and paying no price, the notion of balance and restraint goes out the window.
The rules of economic globalization are likewise designed to benefit the rich: they encourage competition among countries for business, which drives down taxes on corporations, weakens health and environmental protections, and undermines what used to be viewed as the “core” labor rights, which include the right to collective bargaining. Imagine what the world might look like if the rules were designed instead to encourage competition among countries for workers. Governments would compete in providing economic security, low taxes on ordinary wage earners, good education, and a clean environment—things workers care about. But the top 1 percent don’t need to care.
