Whistling Past the Graveyard on the Way to the Congressional Budget Office

It's a story of fiddling and burning and you know the end:

If only a few countries faced these problems, the solution would be easy. Unlucky countries would trim budgets and resume growth by exporting to healthier nations. But developed countries represent about half the world economy; most have overcommitted welfare states. They might defuse the dangers by gradually trimming future benefits in a way that reassured financial markets. In practice, they haven't done that; indeed, President Obama's health program expands benefits. What happens if all these countries are thrust into Greece's situation? One answer -- another worldwide economic collapse -- explains why dawdling is so risky.
