Newt is right, again

Newt Gingrich is not the most innocent dove in the world. But he and Peter Ferrara are right:

Mr. Obama's tax plan includes creating or expanding nine or more federal income tax credits mostly focused on low- and moderate-income earners, with an estimated cost of $1.3 trillion over 10 years. These tax credits are provided for certain social purposes, such as child care, health care, education, housing and retirement. Buried amid these is Mr. Obama's purported tax cut for the middle class.

For the bottom 40% of income earners, who pay no federal income taxes on net today, these refundable income tax credits will not reduce tax liability but instead result in new checks from the federal government for the targeted social purposes. That's not a tax cut. It's welfare.

These tax credits will do little or nothing to promote economic growth because they do not reduce marginal tax rates -- the rate on the next dollar of income -- to provide powerful, meaningful incentives for productive activities such as investment, entrepreneurship and work. A tax credit is effectively a cash grant that can only affect incentives up to the amount of the grant. Indeed, such tax credits would likely reduce economic growth because the credits are phased out as income rises, and so effectively impose higher marginal tax rates over those income levels.

For a real middle-class tax cut, we should cut the 25% income tax rate that now applies to single workers earning $32,550 to $78,850, and married couples earning $65,100 to $131,450. We should reduce that rate down to the 15% rate paid by workers below these income levels. That would, in effect, establish a flat-rate tax of 15% for close to 90% of American workers.

Marginal tax rates for middle-income families in the 25% tax bracket are too high. Add in effective payroll tax rates of 15% and state income taxes, and these workers are laboring under marginal tax rates of close to 50%. No wonder middle-income wage growth has slowed sharply. Reducing the marginal tax rates for these middle-income earners would lead to income increases for middle-income workers, just as reducing excessive marginal tax rates for higher-income workers did, going all the way back to the Kennedy tax cuts of the 1960s.

This 40% cut in middle-class income tax rates would provide a powerful boost to the economy, greatly expanding incentives for savings, investment and work. This would be much more effective than Mr. Obama's tax plan with it's $1.3 trillion in redistributive tax credits, as well as yet another so-called stimulus package based on another $300 billion or more in increased government spending.
