— I discovered evidence showing how much colleges have changed over time, and one reason they have become so expensive. Administrative staff have exploded in size relative to the growth in the number of students, or faculty. Enrollment expanded somewhat since the mid-1960s at OU, as did research activity, perhaps justifying a 50 percent increase or even doubling in administrative staff. Today, I count over 70 persons in OU’s “Advancement” operation, with still others in other areas involved in lobbying or as private contractors. University enrollments are lower today than in 2010, and school closings are likely to rise meaningfully.
