By that standard, the Simpson-Bowles deficit commission, whose work is now being treated as if it were the gold standard of fiscal seriousness, was in fact deeply unserious. Its report “was one big magic asterisk,” Bob Greenstein of the Center on Budget and Policy Priorities told The Washington Post’s Ezra Klein. So is the much-hyped proposal by Paul Ryan, the G.O.P.’s supposed deep thinker du jour, to replace Medicare with vouchers whose value would systematically lag behind health care costs. What’s supposed to happen when seniors find that they can’t afford insurance?

What would real action on health look like? Well, it might include things like giving an independent commission the power to ensure that Medicare only pays for procedures with real medical value; rewarding health care providers for delivering quality care rather than simply paying a fixed sum for every procedure; limiting the tax deductibility of private insurance plans; and so on.

And what do these things have in common? They’re all in last year’s health reform bill.

That’s why I say that Mr. Obama gets too little credit. He has done more to rein in long-run deficits than any previous president. And if his opponents were serious about those deficits, they’d be backing his actions and calling for more; instead, they’ve been screaming about death panels.

Now, even if we manage to rein in health costs, we’ll still have a long-run deficit problem  a fundamental gap between the government’s spending and the amount it collects in taxes. So what should be done?

This brings me to the seventh word of my summary of the real fiscal issues: if you’re serious about the deficit, you should be willing to consider closing at least part of this gap with higher taxes. True, higher taxes aren’t popular, but neither are cuts in government programs. So we should add to the roster of fundamentally unserious people anyone who talks about the deficit  as most of our prominent deficit scolds do  as if it were purely a spending issue.

The bottom line, then, is that while the budget is all over the news, we’re not having a real debate; it’s all sound, fury, and posturing, telling us a lot about the cynicism of politicians but signifying nothing in terms of actual deficit reduction. And we shouldn’t indulge those politicians by pretending otherwise.
