Concerning Challenger, at least according to Feynman, the problem was one of organization more than actual technical (in)competency. From what I have seen, there is something fundamentally wrong in the finance sector - and I don't think it has much to do with morality. It has more to do with the fact that they have so much money that they can afford to do things in very stupid ways. Retail is e.g. most likely far more sophisticated in their usage of IT than the big investment banks. Banks are full of custom systems that are 10 times less efficient at solving problems that have become commodities everywhere else. The fact that they have so much money working the way they work suggests that some rent positions are at play. Changing this would require a cultural shift that is not likely to happen if they take people from a similar cultural background IMO.
