It's the salaries, but only that. There are occasional sudden unscheduled boosts in salaries for administrators, apparent rewards for well...what?

Then there are the little deals made between administrators involving getting hired part-time at high salary after retirement. There are all sorts of ways the admins bleed the system. The U is a corporate world with a tendency toward corporate ethics in some sectors.
