In 2020/2021 the estimated beninternational students before graduation was £41.9 billion
Universities as a whole contribute £100 billion a year to the economy.
Graduate uplift on earnings, through the extra paid in tax over a lifetime, more than covers fees.
Fees were supposed to rise with RPI, but have been frozen for 10 years. That's 10 years of effectively cutting funding for Higher Education. When you add in our ridiculous "hostile environmen", Brexit & changes to visas, the war on arts & humanities (the cheaper courses that actually contributed to the more expensive course) and the mismanagement of investment in buildings & land by many institutions then it's not surprising that Universities are cutting staff & courses to "balance their books".
It's a false economy to cut funding for education at any level, but I don't think the burden should fall on students.
