My personal view is not that bankruptcy is the answer; just that it will be the inevitable result.
The only question is whether a few large Wall St. firms will go bankrupt, causing pain to many other financial institutions and governments, or whether America itself will go near-bankrupt as a result of taking the losses on themselves.
And no, I don't have a lot of respect for Buffett, ever since he fought the inheritance (death) tax being repealed, which is after all double taxation, and from which his company personally benefits.
His insurance companies make billions on pricy insurance sold to small and medium sized business owners who are nearing the end of their life (you buy the insurance so that when you die, the company does not have to be liquidated in order to pay the IRS).
