Our financial catastrophe, like Bernard Madoff’s pyramid scheme, required all sorts of important, plugged-in people to sacrifice our collective long-term interests for short-term gain. The pressure to do this in today’s financial markets is immense. Obviously the greater the market pressure to excel in the short term, the greater the need for pressure from outside the market to consider the longer term. But that’s the problem: there is no longer any serious pressure from outside the market. The tyranny of the short term has extended itself with frightening ease into the entities that were meant to, one way or another, discipline Wall Street, and force it to consider its enlightened self-interest…

How does this happen? How can the person in charge of assessing Wall Street firms not have the tools to understand them? Is the S.E.C. that inept? Perhaps, but the problem inside the commission is far worse — because inept people can be replaced. The problem is systemic. The new director of risk assessment was no more likely to grasp the risk of Bernard Madoff than the old director of risk assessment because the new guy’s thoughts and beliefs were guided by the same incentives: the need to curry favor with the politically influential and the desire to keep sweet the Wall Street elite.

And here’s the most incredible thing of all: 18 months into the most spectacular man-made financial calamity in modern experience, nothing has been done to change that, or any of the other bad incentives that led us here in the first place.
