A brief word on Warren Buffets testimony on Thursday. I thought it amounted to an admission of moral bankruptcy. He more or less removed himself for any responsibility for the financial crisis or indeed for Moody's lousy ratings. They needed to "tweak their models" he said. What utter nonsense, he must have known that they were receiving commissions for their work and that unless the ratings issued were "AAA" then no further work would be headed their way. It was their duty to issue AAA ratings on CDO's and whatever other products they found in front of them. He knew.. He knew that the whole system was crooked, he isn't the kindly grandfather figure he tries to make out... what he is is yet another wall street crook.
