In the last lap of his limping campaign, John McCain is claiming that Barack Obama "believes in redistributing wealth." The problem with this charge is not that it's untrue. It's that McCain—and most of his supporters—favor redistribution, too.
Government redistributes wealth to some extent by its very existence, since it's impractical for citizens to pay for or benefit from it in equal proportion, even if that were desirable. So long as you have a system of taxation and a spending on public goods like education and roads, some people will do better in the bargain than others. The real questions are whether public policy consciously tries to affect the distribution of wealth, how much it tries to change it, and in what direction.
Redistribution has a "from" side—taxation—and a "to" side—spending. On the "from" side, the notion that government should use taxation to increase rather than decrease equality is hardly Marxist. In The Wealth of Nations, Adam Smith begins his section on taxation with the following maxim: "The subjects of every state ought to contribute towards the support of the government, as nearly as possible, in proportion to their respective abilities." To ask otherwise, Smith writes, would be obviously unfair.
Until the 20th century, the bulk of government revenues came from tariffs, which are regressive, meaning that they redistribute income away from the poor. The progressive principle was enshrined in American practice with the arrival of the federal income and inheritance taxes. The champion of these policies was none other than John McCain's hero, Teddy Roosevelt. We got progressive income taxes with the passage of the 16th Amendment in 1913. The federal estate tax we have today came in 1916.
Even in his current proposals, McCain adheres to his hero's principles. Unlike George W. Bush, John McCain supports the retention of an estate tax (he favors reducing it to 15 percent on estates above $5 million). McCain opposes the Flat Tax, which would repudiate progressivity (though with a $46,000 exemption, it would still redistribute income). Some of us still remember the John McCain who opposed Bush's 2001 tax cut on the argument that it was unfairly tilted toward the rich.
On the "to" side of the ledger, large-scale redistributive policies owe their existence to the other President Roosevelt. The biggest and most important of these is Social Security. FDR understood that an income support program that was too explicitly redistributionist would be unlikely to survive politically, which is why everyone who works and pays into the system has a right to benefits. But the Social Security Administration does quietly shift money from relatively richer to relatively poorer—even if recent research indicates that it may do so less than intended, largely because poor people have shorter life expectancies.
Curiously, the most prominent proponents of more-aggressive wealth redistribution have been Robin Hoods of the right. Milton Friedman is considered the father of the negative income tax, a 1960s-era proposal to simply give cash to the poor. Richard Nixon proposed a version of this plan in 1973. The idea was that simply writing checks would be preferable to more bureaucratic programs like welfare. Our most explicit redistributive program today is probably the Earned Income Tax Credit, which supplements the incomes of people who work but don't earn enough to escape poverty on their own. Gerald Ford signed this bill into law, and Ronald Reagan greatly expanded it.
John McCain has long favored the EITC, calling it "a much-needed tax credit for working Americans." McCain doesn't support the repeal of Social Security, or Medicare, or a raft of other wealth-spreading programs like food stamps. McCain also supports new redistributive measures, such as a tax credit to help people with lower incomes purchase health insurance.
McCain might respond by saying it is not the principle of redistribution that makes Obama's policies objectionable but rather the extent of them. Socialistic Sweden, with its generous social benefits and a government consuming around 55 percent of GDP, exists on the same continuum with the mildly distributive United States, where you can't get by on welfare payments and where total government spending is in the range of 30 percent of GDP. McCain is trying to argue that an Obama presidency would lead us toward the Swedish model.
Perhaps, but there's little in Obama's background or writings to suggest that he favors more-ambitious redistributive policies. His most expensive new social program is an expansion of health care coverage that would not create a universal entitlement (as many Democrats want to do). It has been credibly priced at less, or only slightly more than McCain's plan. There's little reason to think that Obama would depart from the bipartisan consensus that has favored federal spending at approximately the same level for the past 40 years.
