Republicans want a tax cut, but they don’t want to fully pay for it and may be willing to increase the deficit by $1.5 trillion over 10 years. This would continue a troubling cycle, economist Jared Bernstein writes, in which supposed fiscal conservatives “use the deficit argument to block spending, promote fiscal austerity, and small government, conveniently tossing deficit concerns aside when it comes to tax cuts.”

You’ll hear arguments about how increased economic growth will make up for the budgetary effects of the tax cuts, but don’t believe them. “Our fiscal history on this point is clear: Cutting taxes loses revenues, which, unless offset by higher taxes elsewhere or spending cuts, increases the budget deficit, which in turn raises the debt.” When this happens again, and the promised growth effects don’t materialize, the tax cutters will go back to pushing for spending cuts.

The country faces a number of serious challenges, including an aging population that by itself will require increased government spending, and we need a tax policy that does more than drive up the deficit. “The problem with structural deficits — ones that go up even in good times — is that they reveal that we’re unwilling to raise the necessary revenues to support the government we want and need. This enables those who whose goal is to shrink government to point to deficits and debt as their proof that we can’t afford it, whatever ‘it’ is, except when ‘it’ is tax cuts.” (New York Times)
