Who will be the next CEO for Goldman Sachs

[ecbb]

昨天读了一篇有趣的文章，说Lloyd Blankfein 为了keep the profit high, turn an investment bank into a hedge fund. And will pick one of the following three as his successor:
Gary D. Cohn
Harvey M. Schwartz
John S. Weinberg

It is pretty funny that if the investment bank doesn't operate as a hedge fund, couldn't make the profit they expected.
