The benefits of repealing Glass-Steagall

according to Tyler Cowen:

Most of all, the Act enabled financial diversification and thus it paved the way for a number of mergers. Citigroup became what it is today, for instance, because of the Act. Add Shearson and Primerica to the list. So far in the crisis times the diversification has done considerably more good than harm. Most importantly, GLB made it possible for JP Morgan to buy Bear Stearns and for Bank of America to buy Merrill Lynch. It's why Wachovia can consider a bid for Morgan Stanley. Wince all you want, but the reality is that we all owe a big thanks to Phil Gramm and others for pushing this legislation. Brad DeLong recognizes this and hail to him. Megan McArdle also exonerates the repeal of Glass-Steagall.
