Re Unis, lots have become degree factories rather than centres of teaching/research excellence. They're also dumbing down degree classifications given the sheer number of people getting First's these days.
My son went to one that was in the "top ten" in the country for his chosen subject, Maths. Over the 3 years he never met any lecturer/professor etc in person, not even his "personal tutor". Yes, he saw them "in person" in lectures, but they were on the stage presenting the lecture. All the seminars, tutorials, etc were run by phd students. Most of the lectures were regurgitated having been written several years earlier by other lecturers.
That kind of thing really isn't the "top quality" education that our young people are paying for.
We'd really be better concentrating on the "in demand" workplace degrees, i.e. STEM etc at the top Unis, and charging more. The "lesser" unis can be converted back to Polytechnics or colleges to provide vocational/professional training courses as they used to do, offering day release/evening/weekend courses to workers etc to study alongside work, where employers would pay for the course fees.
Even if the "top" degree courses cost more, then the students are more likely to be higher earners so more likely to actually repay the course fees via student loan repayments, than all the students who've taken lower quality courses who never earn enough to pay much of their student loan off.
