Was Gordon Gecko wrong??!?

Could we have possibly misunderstood the point of Wall Street? Greed was good, right? Especially if it's greed in service of - greedy individuals!

And then the word "theoretically" becomes very important. I have attended many conferences on quantitative finance, at which professors and practitioners describe their latest models for derivative instruments and the like. All the time I'm sitting in the audience thinking that these models are far too simplistic and based on countless unrealistic assumptions. I tell people that these instruments are dangerous, that no one understands the risks. But no one cares.

As long as people are compensated hugely for taking risks with other people's money, and do not suffer equally on the downside, then those risks will inevitably become outrageous. Whether markets are efficient or not I don't know for sure, but I do know that if there's a way for someone to make money at another's expense, he will. In spades. I want out.
