Today marks the 10-year anniversary of the passage of the repeal of the 1933 Glass-Steagall Act and related legislation. It is an anniversary worth noting for what it teaches us about forestalling financial crises, the consequences of maniacal deregulation, and the out-of-control political power of the megafinancial institutions. The repeal of Glass-Steagall removed the legal prohibition on combinations between commercial banks on the one hand, and investment banks and other financial services companies on the other. Glass-Steagall's strict rules originated in the U.S. government's response to the Depression and reflected the learned experience of the severe dangers to consumers and the overall financial system of permitting giant financial institutions to combine commercial banking with other financial operations.
