Read the whole piece here. My favoriate blurb follows:
In fact, I have some sympathy with the view that mortgage lenders "perform a valuable social service through their loans." That's why, when they stop doing that and become predators, equity strippers, and bubble-blowers instead of valuable social service providers, I like seeing BK judges slap them around. Everybody talks a lot about moral hazard, and the reality is that you're a lot less likely to put a borrower with a weak credit history, whose income you did not verify and whose debt ratios are absurd, into a 100% financed home purchase loan on terms that are "affordable" only for a year or two, if you face having that loan restructured in Chapter 13. If you are aware that your mortgage loan can be crammed down, I'm here to tell you that you will certainly not "forget" to model negative HPA in your ratings models, and will probably pay more than a few seconds' attention to your appraisals. You might even decide that, if a loan does get into trouble, you're better off working it out yourself, via forbearance or modification or short sale, rather than hanging tough and letting the BK judge tell you what you'll accept. That would be a major bummer, right?
