jws, some of it is that, but I would gather it's also a way to make some people feel special, not like the rest of the poor drones who have to fight for parking, fight for seats, wait in line for the bathroom, etc.
For many years before I dropped out, if some privilege was "special" (as in you had to apply to the elders, for instance) I hated it. Just a way to have a caste system, without the poor publisher drones understanding what is really going on. They go along with it, and in the meanwhile, get disrespected.
