Krugman on the Austerity Moralizers, and how they're full of @#$%

From "Mugged by the Moralizers". This is a quick handy guide, the next time someone lectures you about the deficit, and the role of Government in trying to fix it:

The years leading up to the 2008 crisis were indeed marked by unsustainable borrowing, going far beyond the subprime loans many people still believe, wrongly, were at the heart of the problem. Real estate speculation ran wild in Florida and Nevada, but also in Spain, Ireland and Latvia. And all of it was paid for with borrowed money.

This borrowing made the world as a whole neither richer nor poorer: one person’s debt is another person’s asset. But it made the world vulnerable. When lenders suddenly decided that they had lent too much, that debt levels were excessive, debtors were forced to slash spending. This pushed the world into the deepest recession since the 1930s. And recovery, such as it is, has been weak and uncertain — which is exactly what we should have expected, given the overhang of debt.

The key thing to bear in mind is that for the world as a whole, spending equals income. If one group of people — those with excessive debts — is forced to cut spending to pay down its debts, one of two things must happen: either someone else must spend more, or world income will fall.

Yet those parts of the private sector not burdened by high levels of debt see little reason to increase spending. Corporations are flush with cash — but why expand when so much of the capacity they already have is sitting idle? Consumers who didn’t overborrow can get loans at low rates — but that incentive to spend is more than outweighed by worries about a weak job market. Nobody in the private sector is willing to fill the hole created by the debt overhang.

So what should we be doing? First, governments should be spending while the private sector won’t, so that debtors can pay down their debts without perpetuating a global slump. Second, governments should be promoting widespread debt relief: reducing obligations to levels the debtors can handle is the fastest way to eliminate that debt overhang.

But the moralizers will have none of it. They denounce deficit spending, declaring that you can’t solve debt problems with more debt. They denounce debt relief, calling it a reward for the undeserving.
