Last week, in a CNBC interview, Sanford I. Weill, the former chairman of Citigroup, said that America should separate investment banking from commercial banking. This separation, of course, was the prime purpose of the Glass-Steagall Act of 1933, a piece of legislation that Mr. Weill and other bankers had successfully watered down, with Alan Greenspan’s support, before Mr. Weill helped engineer its official demise in 1999. Now, Mr. Weill, the creator of what was once the largest financial conglomerate in the world, suggests that Citigroup and others should be broken up. Banks can no longer “be too big to fail,” he told CNBC.
But what was most eye-catching was Mr. Weill’s claim that the conglomerate model “was right for that time.” Nothing could be further from the truth.
