Well, it's Krugman. Government spending and Fed money printing are his two magic cures for everything that ails the economy. (Note that his column at least used to be titled "The Conscience of a Liberal". He's writing primarily as a liberal, not as an economist.)

Under current conditions, though, he could in fact be right. But there are two problems with government borrowing. First, while there may be very good things to spend the money on, instead the spending decisions are going to be made by Congress, politically rather than economically. That's a recipe for a bunch of wasteful spending, with perhaps some good things done as well, but the good things are almost a result of chance.

Second, Congress may be right to decide to spend money now, but the time comes when it is no longer time to borrow and spend. Will Congress stop when it's time to stop? History does not lead to optimism here.

This time may in fact be different. But it's different a lot less often than people say it is, especially people who say "it's different" in order to throw away rules that keep them from doing what they want.
