The Great Depression 2.0

James Pethokoukis calculates the cost of doing nothing:

What would be the dollar cost of not bailing out Wall Street? Try a number north of $30 trillion. (The awful math is detailed below.) That's why Hank Paulson and Ben Bernanke were so scared last week. And, yes, I think "scared" isn't too strong a word. You don't think they convened an emergency nighttime meeting of congressional leaders and then walked out with something close to a blank check for a trillion bucks because they thought we were headed for an outright recession, even a fairly nasty one?

This could be it, couldn't it?
