If you think to yourself, "Okay, so the bank failed. Let it go. Don't go and build a big gubment financial regulatory authority -- it's overkill," you'd be kidding yourself. Ezra Klein writes:
Banks don't fail. They explode. They take other banks down with them. The easiest analogy is to a bomb. What happened with Lehman Brothers is that the bomb went off, and it took the financial sector with it, at least temporarily. That's, well, one way of handling a bomb. But it's not the preferred way. The preferred way is to defuse it.
