Americans have been watching protests against oppressive regimes that concentrate massive wealth in the hands of an elite few. Yet in our own democracy, 1 percent of the people take nearly a quarter of the nation’s income—an inequality even the wealthy will come to regret....
...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....
...None of this should come as a surprise—it is simply what happens when a society’s wealth distribution becomes lopsided. The more divided a society becomes in terms of wealth, the more reluctant the wealthy become to spend money on common needs. The rich don’t need to rely on government for parks or education or medical care or personal security—they can buy all these things for themselves. In the process, they become more distant from ordinary people, losing whatever empathy they may once have had. They also worry about strong government—one that could use its powers to adjust the balance, take some of their wealth, and invest it for the common good. The top 1 percent may complain about the kind of government we have in America, but in truth they like it just fine: too gridlocked to re-distribute, too divided to do anything but lower taxes....
...But one big part of the reason we have so much inequality is that the top 1 percent want it that way. The most obvious example involves tax policy. Lowering tax rates on capital gains, which is how the rich receive a large portion of their income, has given the wealthiest Americans close to a free ride. Monopolies and near monopolies have always been a source of economic power—from John D. Rockefeller at the beginning of the last century to Bill Gates at the end. Lax enforcement of anti-trust laws, especially during Republican administrations, has been a godsend to the top 1 percent. Much of today’s inequality is due to manipulation of the financial system, enabled by changes in the rules that have been bought and paid for by the financial industry itself—one of its best investments ever....
