"College students and their families have struggled to pay for the rising cost of tuition, a cost that has been driven in part by swelling administrative expenses. Over a 20-year period, the growth in administrative personnel at institutions of higher education has outpaced the growth in both faculty and student enrollment."

"One reason administration at public institutions has grown faster may be that bureaucracies tend to expand their staff and programs over time, regardless of need."
