I think it's similar to a thread we had here recently about why it's impossible to unionize tech workers. Basically, most tech workers don't like other tech workers (or other people, really) very much, so there's very little camaraderie of the sort you need to get people to team up and take on a shared enemy. Instead, we all think we're smarter than the other guy, so he'll be the one who gets fired while I thrive in the new situation.
