I typo'ed. I said "management isn't guilty" but I meant to type "management isn't guilt-free".
I also agree that there people who profit, but I encourage you to see that as part of the dynamics rather than an exceptional case that somehow happens every time. It is perfectly predictable that people who will try to profit from this will enter the system, in ways both monetary and psychological. It's merely the n'th step, not some sort of surprise.
Also, I don't think that "those places attract a certain type of managers" is much of an excuse for those managers.
