Krugman’s Nobel-y advice to fix the economy:

It’s now clear that rescuing the banks is just the beginning: the nonfinancial economy is also in desperate need of help.
And to provide that help, we’re going to have to put some prejudices aside. It’s politically fashionable to rant against government spending and demand fiscal responsibility. But right now, increased government spending is just what the doctor ordered, and concerns about the budget deficit should be put on hold.
[…]
Will the next administration do what’s needed to deal with the economic slump? Not if Mr. McCain pulls off an upset. What we need right now is more government spending — but when Mr. McCain was asked in one of the debates how he would deal with the economic crisis, he answered: “Well, the first thing we have to do is get spending under control.”
If Barack Obama becomes president, he won’t have the same knee-jerk opposition to spending. But he will face a chorus of inside-the-Beltway types telling him that he has to be responsible, that the big deficits the government will run next year if it does the right thing are unacceptable.
He should ignore that chorus. The responsible thing, right now, is to give the economy the help it needs. Now is not the time to worry about the deficit.
