I have no idea why anyone would say "research generates no revenues" when most universities have systems to spin out viable research and profit from it. Universities quite literally profit financially from patented research funded by taxpayers. The government gets no direct return on this, and the usual argument is that it increases economic activity and raises the tax take - which may be true, but it's still a uniquely privileged position.

But most universities are more about property speculation and bequest farming than they are about education or R&D.

The system is entirely corporatised and often predatory. Professors are only as valuable as the grant income they generate, adjuncts are gig economy labour, students are a barely-tolerated annoyance, and property speculation and "administration" are considered the central mission.
