This part sounds ever so familiar (same problem in large corporations, public schools, law enforcement, etc.)
The Goldwater Institute points to a third poison to add to rising prices and declining productivity: administrative bloat. Between 1993 and 2007 spending on university bureaucrats at America’s 198 leading universities rose much faster than spending on teaching faculty. Administration costs at elite private universities rose even faster than at public ones. For example, Harvard increased its administrative spending per student by 300%. In some universities, such as Arizona State University, almost half the full-time employees are administrators. Nearly all university presidents conduct themselves like corporate titans, with salaries, perks and entourages to match.
