On one side, we’ve been warned, over and over again, that “bond vigilantes” will turn on the U.S. government unless we slash spending immediately. Yet interest rates remain low by historical standards; indeed, they’re lower now than they were in the spring of 2009, when those dire warnings began.

On the other side, we’ve been assured that spending cuts would do wonders for business confidence. But that hasn’t happened in any of the countries currently pursuing harsh austerity programs. Notably, when the Cameron government in Britain announced austerity measures last May, it received fawning praise from U.S. deficit hawks. But British business confidence plunged, and it has not recovered.

Yet the obsession with spending cuts flourishes all the same — unchallenged, it must be said, by the White House.

I still don’t know why the Obama administration was so quick to accept defeat in the war of ideas, but the fact is that it surrendered very early in the game. In early 2009, John Boehner, now the speaker of the House, was widely and rightly mocked for declaring that since families were suffering, the government should tighten its own belt. That’s Herbert Hoover economics, and it’s as wrong now as it was in the 1930s. But, in the 2010 State of the Union address, President Obama adopted exactly the same metaphor and began using it incessantly.

And earlier this week, the White House budget director declared: “There is an agreement that we should be reducing spending,” suggesting that his only quarrel with Republicans is over whether we should be cutting taxes, too. No wonder, then, that according to a new Pew Research Center poll, a majority of Americans see “not much difference” between Mr. Obama’s approach to the deficit and that of Republicans.

So who pays the price for this unfortunate bipartisanship? The increasingly hopeless unemployed, of course. And the worst hit will be young workers — a point made in 2009 by Peter Orszag, then the White House budget director. As he noted, young Americans who graduated during the severe recession of the early 1980s suffered permanent damage to their earnings. And if the average duration of unemployment is any indication, it’s even harder for new graduates to find decent jobs now than it was in 1982 or 1983.

So the next time you hear some Republican declaring that he’s concerned about deficits because he cares about his children — or, for that matter, the next time you hear Mr. Obama talk about winning the future — you should remember that the clear and present danger to the prospects of young Americans isn’t the deficit. It’s the absence of jobs.

But, as I said, these days Washington doesn’t seem to care about any of that. And you have to wonder what it will take to get politicians caring again about America’s forgotten millions.
