Two things

Public universities are always underfunded.

Universities can get more money by putting the cost on the students and then they cover it with gov grants and loans.

Except, Yale is a private university, not public, while very few universities in the UK are private (https://en.wikipedia.org/wiki/Category:Private_universities_... lists 8 and https://studying-in-uk.org/private-universities-in-uk/ lists 11) so 2b3a51 almost certainly means public college teaching experience in the UK.
