This.
Everyone benefits:
18-21 year olds get three extra years to piss about before facing the workplace.
Government gets to keep them off the unemployment figures.
Parents get to boast about their beloved DC going to university.
Universities benefit from bums on seats to pay for a massively bloated 'administocracy' - a whole army of lanyard wearers with cushy jobs (back-office jobs, not the actual lecturers at the coal face who get a crappy deal). All these keyboard-tappers didn't exist in universities half a century ago. Universities are now businesses, primarily about the money and the staff. And the more staff, the bigger the institution, the more the top-bosses feel justified in paying themselves.
The right-wing media love that it is a "loan" not a proper fair graduate tax.
The rich love that their offspring never need this debt because they pay up front.
Employers now get to employ "graduates" but still only pay them what A-level holders or even GCSE school-leavers used to earn.
It is all a big scam, and will come crashing down in a pile of rubble when demographics change and Gen Alpha see through it and choose not to go.
Uni should go back to being for only the highly-academic 2-5% of the population who want to write papers and study for the sake of it.
Most graduate-only jobs should go back to being A-Level-or-Equivalent, and train on the job.
