Oh please. The idea that you can spend your way out of debt has been shown to be disastrous over and over, and yet like the Marxist "scientists" before them these Neo-Keynesians are going to claim everything is peachy until even the slowest among us can see they're wrong (and not scientists, either). But like any good faith healer they'll say "You didn't do it hard enough". Does that sound familiar?
In the short run austerity is painful. In the long run it's the only option, and putting off the pain only makes it worse when you're out of options. Either you do it honestly by cutting expenditures, or you do it the normal way by printing money.
The idea you can derive globally applicable lessons from a country the size of Cleveland is a bit daft.
