Because of this:
Senior administrators now officially outnumber faculty at UC. And would you like to know how much the university that is supposedly broke pays its useless paper-pushers? See here. The only job of these bureaucrats is to make the lives of the faculty and the students so miserable that very little actual education takes place. And they are amply compensated for producing reams of useless paperwork.
This is why it is not at all surprising that University of California has been circling the bowl for a while now.
