The advice I gave in the last 15 years was always - NEVER go to University for the sake of it - or merely to bump up your qualifications.
Do NOT go just for the social life.
DO go if your specified profession demands a degree.
DO go if you have a love for your subject and would suffer a sense of loss if you were not to follow a course of further study.
DO remember that with lost income; accommodation costs; course fees, books etc - you may be looking at a six figure debt.
The problem is that Labour's utterly idiotic policy of boosting numbers at uni - often in fairly worthless courses of study - the market has been saturated to the extent that employers feel obliged to demand a degree for jobs which really only require 4 passes at GCSE! It is yet another, huge leftist mess!
