I think it might be more like what I read in a book about Hughes one time, that basically when he was at his craziest he was still making incredible amounts of money and the theory was that once you reach a certain size/power it takes on a life of its own and you continue to make money despite fucking up a lot - although one can see a lot of countervailing examples I think in a case of some of the companies I've been at simple economic inertia meant they still did well.
