Blankfein faced a vote on Friday at the annual shareholder meeting to have him stripped of his chairman's title. Many of the other big Wall Street firms have already separated the chairman and CEO roles as part of improving governance structure, and institutional heavyweights including CalPERS had voted to force Blankfein to give up the chairman post. Goldman's board was dead set against the change, and while the investment bank is yet to prevail against the SEC, Goldman Sachs did prevail in defeating the shareholder proposal to make Blankfein give up the dual title. Warren Buffett has said as part of his support of Goldman Sachs, that if he had a brother, he would want the brother to be like Lloyd Blankfein, and so, with the dual titles of CEO and chairman to stay on Blankfein's desk, it's almost as if Buffett has twin imaginary brothers.
