Read the following from Paul Krugman in 2003 when the irresponsible people increasing the federal debt (he and I agree here) were Bush and the Republican Congress.
That may sound alarmist: right now the deficit, while huge in absolute terms, is only 2 ? make that 3, O.K., maybe 4 ? percent of G.D.P. But that misses the point. "Think of the federal government as a gigantic insurance company (with a sideline business in national defense and homeland security), which does its accounting on a cash basis, only counting premiums and payouts as they go in and out the door. An insurance company with cash accounting . . . is an accident waiting to happen." So says the Treasury under secretary Peter Fisher; his point is that because of the future liabilities of Social Security and Medicare, the true budget picture is much worse than the conventional deficit numbers suggest.
But we're looking at a fiscal crisis that will drive interest rates sky-high.
As an economist friend commented on this latter statement, "How did that prediction turn out?"
Does this sound like the Paul Krugman writing about the deficit and debt now? Here's from a piece last month:
But what about all that debt we're incurring? That's a bad thing, but it's important to have some perspective. Economists normally assess the sustainability of debt by looking at the ratio of debt to G.D.P. And while $9 trillion is a huge sum, we also have a huge economy, which means that things aren't as scary as you might think.
Here's one way to look at it: We're looking at a rise in the debt/G.D.P. ratio of about 40 percentage points. The real interest on that additional debt (you want to subtract off inflation) will probably be around 1 percent of G.D.P., or 5 percent of federal revenue. That doesn't sound like an overwhelming burden.
Now, this assumes that the U.S. government's credit will remain good so that it's able to borrow at relatively low interest rates. So far, that's still true. Despite the prospect of big deficits, the government is able to borrow money long term at an interest rate of less than 3.5 percent, which is low by historical standards. People making bets with real money don't seem to be worried about U.S. solvency.
