Last week, four senators that include Elizabeth Warren (D-Mass.) and John McCain (R-Ariz.) introduced a bill to reinstate the Glass-Steagall Act.
The 21st Century Glass-Steagall Act, as it's called, would bring back many of the provisions of the former law and strengthen language to limit financial speculation by the big banks, reduce risk, and attempt to end "Too Big to Fail" once and for all.
The original legislation, called The Banking Act of 1933 but commonly referred to as Glass-Steagall, was partly repealed by Congress in 1999 and signed into law by President Bill Clinton. But by the time Glass-Steagall was repealed, the law had already been watered down and full of loopholes that left the U.S. economy highly vulnerable to a financial crisis.
Many economists believe that the partial repeal of this law was responsible for the recent financial crisis.
