The total annual expenditures on refundable "tax credits" would rise over the next 10 years by $647 billion to $1.054 trillion, according to the Tax Policy Center. This means that the tax-credit welfare state would soon cost four times actual cash welfare. By redefining such income payments as "tax credits," the Obama campaign also redefines them away as a tax share of GDP. Presto, the federal tax burden looks much smaller than it really is.
There's another catch: Because Mr. Obama's tax credits are phased out as incomes rise, they impose a huge "marginal" tax rate increase on low-income workers. The marginal tax rate refers to the rate on the next dollar of income earned. As the nearby chart illustrates, the marginal rate for millions of low- and middle-income workers would spike as they earn more income.
Some families with an income of $40,000 could lose up to 40 cents in vanishing credits for every additional dollar earned from working overtime or taking a new job. As public policy, this is contradictory. The tax credits are sold in the name of "making work pay," but in practice they can be a disincentive to working harder, especially if you're a lower-income couple getting raises of $1,000 or $2,000 a year. One mystery -- among many -- of the McCain campaign is why it has allowed Mr. Obama's 95% illusion to go unanswered.
There's a reason I didn't support McCain initially; his Bush-like inability to articulate a policy position, particularly when it comes to economic issues, is among the biggest. Senator, please, have someone write some lines, memorize them, and spit them back out. Please.
