Here's an interesting question: How many other Ponzi schemes and similar frauds of which we are as of yet unaware have managed to survive so far due to the trillions of bailout dollars handed out?
Can you see how this question undermines the effect of Helicopter Ben Bernake's strategy of dumping cash out of a helicopter -- why the effect of stimulus has widely been described as pushing on a noodle? With Madoff, the bailouts may have delayed the final reckoning by a couple of months. For less colossal scams, it may delay them for even longer. But there will be a reckoning, so who (besides the government) wants to pour good money after bad?
