I know this is a common argument, but I would love to see some hard data about expenditures on administrative staff in Universities. Every time I look for this, I find that the expenditures on administrators has mostly gone up in the Health Care sectors of Higher Education. Instructional, student affairs and research administrators are up modestly.

Do you have any sources or citations to support the broad claims about increases in administrators or broad surplus revenue? As non-profits, if tuition is going up and all other fund sources are flat, then expenditures have to go up as well, there is no owner's profit to absorb excess revenue.

The best data I has is from the Education department, see the last part of this chart (Expenditure per full-time-equivalent student in constant 2022-23 dollars):
