Moral Hazard Redux: Why Bail Out the Banks?

Back in May, Redfin readers said loud and clear that they opposed Congress’ bailing out homeowners struggling to pay their mortgages.
“If I can’t pay my rent I don’t get to keep my apartment and nobody is going to bail me out. Why should I be forced to pay their mortgage?” asked Greg.
Well, now it appears that Congress is going to bail out the financial institutions that made these dire mistakes in the first place. Or rather, we, the taxpayers, are going to do so. The country’s financial survival is at stake, we are told, so in this case, is it necessary? Folks on angryrenter.com don’t think so; they say it’s welfare for Wall Street.
Readers (among them David, dg, morgan and sb) have argued in the past that if buyers facing foreclosure aren’t punished, they might feel they can do it again with impunity (“moral hazard.”) Does this apply to the financial institutions? Or is there no choice in order to keep world financial markets alive? (Photo: digitalshay on flickr.)
