Bureaucracy has gone up, sure, but not nearly as much as the number of people seeking PhDs.
That also used to be much less common back in the day.
Assuming I'm reading them correctly, these seem to be Yale's numbers:
2003: 2294 Arts & Sciences PhD students and 3500 administrators + managers
2021: 2895 Arts & Sciences PhD students and >5000 administrators + managers
So administrative growth seems to have outpaced PhD student growth by some margin over that time period.
Regardless, the secret to high research productivity (per dollar) at universities is cheap labor from grad students and postdocs.
