Mr. Obama answered by citing rich hedge fund managers. Raising the capital gains tax is necessary, he said, "to make sure . . . that our tax system is fair and that we are able to finance health care for Americans who currently don't have it and that we're able to invest in our infrastructure and invest in our schools. And you can't do that for free."
But Mr. Gibson had noted that higher rates yield less revenue. So the news anchor tried again: "But history shows that when you drop the capital gains tax, the revenues go up?" Mr. Obama responded that this "might happen or it might not. It depends on what's happening on Wall Street and how business is going." And then he went on a riff about John McCain and the housing market.
This is instructive. The facts about capital gains rates and revenues are well known to our readers, but we'll repeat them as a public service to the Obama campaign. As the nearby chart shows, when the tax rate has risen over the past half century, capital gains realizations have fallen and along with them tax revenue. The most recent such episode was in the early 1990s, when Mr. Obama was old enough to be paying attention. That's one reason Jack Kennedy proposed cutting the capital gains rate. And it's one reason Bill Clinton went along with a rate cut to 20% from 28% in 1997.
Either the young Illinois Senator is ignorant of this revenue data, or he doesn't really care because he's a true income redistributionist who prefers high tax rates as a matter of ideological dogma regardless of the revenue consequences. Neither one is a recommendation for President.
For her part, Hillary Clinton said that she, too, was open to hiking the capital gains tax rate, just not by as much as her rival. "I wouldn't raise it above the 20% if I raised it at all," she said. Of course, she too promised during Wednesday's debate not to raise "a single tax on middle-class Americans, people making less than $250,000 a year."
Both candidates would have voters believe that taxes on investment income only affect the rich. But that's not what Internal Revenue Service returns show. The reality is that the Clinton and Obama rate increases would hit millions of Americans who make well under $200,000. In 2005, 47% of all tax returns reporting capital gains were from households with incomes below $50,000, and 79% came from households with incomes below $100,000.
The only point of a tax increase (no matter how misguided it may be) is to raise more revenue, but as history has clearly proven, raising the capital gains tax actually lowers government revenue. It appears that some liberal leaders are so preoccupied with building larger government at the cost of the taxpayers that they're willing to ignore the facts.
