And Mr. Obama should just say no, for three reasons.

First, despite years of dire warnings from people like, well, Alan Simpson and Erskine Bowles, we are not facing any kind of fiscal crisis. Indeed, U.S. borrowing costs are at historic lows, with investors actually willing to pay the government for the privilege of owning inflation-protected bonds. So reducing the budget deficit just isn’t the top priority for America at the moment; creating jobs is. For now, the administration’s political capital should be devoted to passing something like last year’s American Jobs Act and providing effective mortgage debt relief.

Second, contrary to Beltway conventional wisdom, America does not have an “entitlements problem.” Mainly, it has a health cost problem, private as well as public, which must be addressed (and which the Affordable Care Act at least starts to address). It’s true that there’s also, even aside from health care, a gap between the services we’re promising and the taxes we’re collecting — but to call that gap an “entitlements” issue is already to accept the very right-wing frame that voters appear to be in the process of rejecting.

Finally, despite the bizarre reverence it inspires in Beltway insiders — the same people, by the way, who assured us that Paul Ryan was a brave truth-teller — the fact is that Simpson-Bowles is a really bad plan, one that would undermine some key pieces of our safety net. And if a re-elected president were to endorse it, he would be betraying the trust of the voters who returned him to office.

Consider, in particular, the proposal to raise the Social Security retirement age, supposedly to reflect rising life expectancy. This is an idea Washington loves — but it’s also totally at odds with the reality of an America in which rising inequality is reflected not just in the quality of life but in its duration. For while average life expectancy has indeed risen, that increase is confined to the relatively well-off and well-educated — the very people who need Social Security least. Meanwhile, life expectancy is actually falling for a substantial part of the nation.
