Frank Rich writes in the New York Times exactly what the Republicans are fighting so hard that they're willing to take the country down for:

On last Sunday’s “60 Minutes,” Obama was already wobbling toward another “compromise” in which he does most of the compromising. It’s a measure of how far he’s off his game now that a leader who once had the audacity to speak at length on the red-hot subject of race doesn’t even make the most forceful case for his own long-held position on an issue where most Americans still agree with him. (Only 40 percent of those in the Nov. 2 exit poll approved of an extension of all Bush tax cuts.) The president’s argument against extending the cuts for the wealthiest has now been reduced to the dry accounting of what the cost would add to the federal deficit. As he put it to CBS’s Steve Kroft, “the question is — can we afford to borrow $700 billion?”

That’s a good question, all right, but it’s not the question. The bigger issue is whether the country can afford the systemic damage being done by the ever-growing income inequality between the wealthiest Americans and everyone else, whether poor, middle class or even rich. That burden is inflicted not just on the debt but on the very idea of America — our Horatio Alger faith in social mobility over plutocracy, our belief that our brand of can-do capitalism brings about innovation and growth, and our fundamental sense of fairness. Incredibly, the top 1 percent of Americans now have tax rates a third lower than the same top percentile had in 1970.

Ah yes, the almighty extension of the Bush tax cut for the very wealthiest Americans. We hear non-stop how ridiculous, how critical, how essential it is to not "raise taxes" (by allowing the tax cut to expire, as scheduled) on the job providers is.

The G.O.P.’s arguments for extending the Bush tax cuts to this crowd, usually wrapped in laughably hypocritical whining about “class warfare,” are easily batted down. The most constant refrain is that small-business owners who file in this bracket would be hit so hard they could no longer hire new employees. But the Tax Policy Center found in 2008, when checking out similar campaign claims by “Joe the Plumber,” that only 2 percent of all Americans reporting small-business income, regardless of tax bracket, would see tax increases if Obama fulfilled his pledge to let the Bush tax cuts lapse for the top earners. The economist Dean Baker calculated that the yearly tax increase at the lower end of that bracket, for those with earnings between $200,000 and $500,000, would amount to $700 — which “isn’t enough to hire anyone.”

That's it--$700! And for that, it's worth sandbagging the country and adding billions to the deficit.

But will a single Democratic politician put it in such stark terms? Of course not.
