I know math is hard, but there simply are not enough administrators to account for all the money. This is the typical union canard.
The truth is, at many colleges, the full time faculty have gobbled up all the salary and benefits, despite teaching a small minority (~25%) of the courses. They limit the pay and hours of the part timers who teach 3/4 of the classes. So the part time faculty are limited to 60% weekly load hours, less per hour, and locked into a cycle of lower middle class or outright poverty.
Typical union greed: They accrue all the goods for a small minority, at the expense of the unemployed or underemployed.
The best part is, even the janitors have tenure. So what gets cut first? Classes - the ones taught by part timers.
Ask me how I know...
