Congress approved landmark legislation today that opens the door for a new era on Wall Street in which commercial banks, securities houses and insurers will find it easier and cheaper to enter one another’s businesses.

The measure, considered by many the most important banking legislation in 66 years, was approved in the Senate by a vote of 90 to 8 and in the House tonight by 362 to 57. The bill will now be sent to the president, who is expected to sign it, aides said. It would become one of the most significant achievements this year by the White House and the Republicans leading the 106th Congress. […]

The opponents of the measure gloomily predicted that by unshackling banks and enabling them to move more freely into new kinds of financial activities, the new law could lead to an economic crisis down the road when the marketplace is no longer growing briskly.

“I think we will look back in 10 years’ time and say we should not have done this but we did because we forgot the lessons of the past, and that that which is true in the 1930’s is true in 2010,” said Senator Byron L. Dorgan, Democrat of North Dakota. “I wasn’t around during the 1930’s or the debate over Glass-Steagall. But I was here in the early 1980’s when it was decided to allow the expansion of savings and loans. We have now decided in the name of modernization to forget the lessons of the past, of safety and of soundness.”

From the New York Times issue of November 5, 1999. I guess that Republicans will complain that Dorgan was grossly inaccurate, because his prediction was a whole year off. You can see Rachel Maddow’s recent interview with Dorgan here.
