The administrators are often former or current faculty. In articles and discussions similar to this there is often this conflict portrayed between faculty and administration but the reality is that they are often the same people. If not from the same institution, then from another institution.

Universities sometimes require or encourage support staff to have higher ed. degrees. Computer tech support positions may require a bachelors degree. Career counseling or academic advising may require a masters. Faculty encourage students to get graduate degrees at the universities they(the faculty member) got their graduate degree from. Politicians and alumni get favors for their families. Universities are practically influence and nepotism laundering machines. Faculty are simply part of the power structure, each trying to improve their position within. Grad school practically selects for individuals who are invested in the institution and will not rock the boat.
