Coruscation

Since the princes are nicer and more impressive, it is easy to be seduced into the belief that they also are more trustworthy. This is false. During the last few years, for example, the princes at Citigroup, Bear Stearns, Goldman Sachs and Lehman Brothers behaved with incredible stupidity while the hedge fund loners often behaved with impressive restraint.

As Sebastian Mallaby shows in his superb book, "More Money Than God", the smooth operators at the big banks were playing with other people's money, so they borrowed up to 30 times their investors' capital. The hedge fund guys usually had their own money in their fund, so they typically borrowed only one or two times their capital.

The social butterflies at the banks got swept up in the popular enthusiasms. The contrarians at the hedge funds made money betting against them. The well-connected bankers knew they'd get bailed out if anything went wrong. The solitary hedge fund guys knew they were on their own and regarded their trades with paranoid anxiety.
