It is obvious that either Germany is going to have to guarantee massive ongoing fiscal transfers to the PIIGS, or Greece and probably Italy are going to have to undergo a massively contractionary austerity program, or they will have to leave the euro. Yet in the face of these three choice--which exclude both each other, and any other mathematically possible outcome--their governments have chosen d: half measures. No, half-measures is too generous. Quarter measures. Window dressing that only covers a single pane.

...

The things that fix economic crises are not always intuitive. As Brad De Long himself once remarked to me, it is nearly impossible to bail out the financial system without also bailing out people who are long assets--aka financiers and rich people. But oh, how that flies in the face of our intuitions! It should be true that the most prosperous system is the one which severely punishes everyone who didn't monitor the soundness of their investments. We feel, very deeply, that financial and economic efficiency should mirror our intuitive sense of justice. And probably it does, mostly, when you're living in a hunter gatherer tribe.

But in a complex world where mistakes are easy and detecting them is not, I just don't think this holds true. The "just world" described above is not some bourgeois paradise; it is the western world during the Great Depression. It was not a better world for everybody; it wasn't even a better world for anybody that I can think of. After it had finished punishing people who made stupid decisions, it went on to wreak brutal vengeance on a lot of people who had been quietly minding their own business. Bank runs can afflict the soundest banks, if depositors panic.

Life savings were wiped out overnight not because depositors hadn't done a good job of choosing a sound bank, but because they'd happened to choose a bank which had credit exposure to other banks that had credit exposure to other banks that were unsound. ...

The solution to the problem turned out to be throwing money at it: going off the gold standard, devaluing, and guaranteeing everyone's bank accounts. Oh, yes, there was moral hazard. There still is. What there aren't, is bank runs that wipe out peoples' life savings overnight, or an unemployment rate of 25%.
