It's my guess that something like 5% of GDP goes to money management and itsattendant friction. I define it broadly - annuities, incentive pay, all trading, etc. Nobody else has used figures that high, but that's my guess.

A lot of people think if you just had more process and more compliance -- checks and doublechecks and so forth -- you could create a better result in the world.
