John Boehner, the speaker of the House, claims to be exasperated. “At some point, Washington has to deal with its spending problem,” he said Wednesday. “I’ve watched them kick this can down the road for 22 years since I’ve been here. I’ve had enough of it. It’s time to act.”

Actually, Mr. Boehner needs to refresh his memory. During the first decade of his time in Congress, the U.S. government was doing just fine on the fiscal front. In particular, the ratio of federal debt to G.D.P. was a third lower when Bill Clinton left office than it was when he came in. It was only when George W. Bush arrived and squandered the Clinton surplus on tax cuts and unfunded wars that the budget outlook began deteriorating again.

But that’s a secondary issue. The key point is this: While it’s true that we will eventually need some combination of revenue increases and spending cuts to rein in the growth of U.S. government debt, now is very much not the time to act. Given the state we’re in, it would be irresponsible and destructive not to kick that can down the road.

Start with a basic point: Slashing government spending destroys jobs and causes the economy to shrink.
