All right, but it's difficult to disagree with a tautology. If the answer to how we trade well is not to trade badly, then the situation truly is dire.
You speak of it in pejorative terms, but to my mind what "risk management" is missing, precisely, is the ability to manage failure. It's a very old kind of hubris to believe that any expedient--whether it's more power in the hands of risk managers, or more in the hands of traders--can categorically prevent a Bear, a Lehman, and so on. The question to address, I think, is not how to prevent such a circumstance from arising, but how to act when it inevitably does.
Is it really a tautology to say that sound business practices involve making sound decisions? That a solid building must be comprised of solid materials?
You start a pitcher that has ability. You run the risk that he'll suffer a rotator cuff injury. In the even it happens, you manage it.
You start your mailman as a pitcher. You finish the first inning behind, 10 - 0. Casey Stengel couldn't make him into Cy Young.
Risk management has and always will be the foremost concern on any competent trader's mind. Capital preservation is rule one in any competent traders mind. He always tells himself, "live to trade another day."
Institutionalized, pooled risk management is going to yield institutional - quality results: lots of mediocrity with the occasional spectacular blowout. Disregard for the money under management leads to foolish risk taking. An implicit government bailout does, too. The pejorative terminology is aimed squarely at the idea that big, complex models can replace competent decision makers. It is certainly not aimed at the concept of risk management.
Once again, you trade your competence, as an individual and as a firm.
On the uphill side of a credit bubble, trading is very easy, mispricing is routine, and risk management is on the mundane side of things. Default correlations seem manageable. When money tightens up, all of a sudden, what once wasn't correlated is, just like the model you showed us in class -- the one that looked like the Golden Gate bridge.
...gotta leave it here for now.
