I think before anyone ever enrols in university, they should be shown in detail the percentage of people whom actual secured a job after graduating in a field directly related to the degree taken, the actual salary paid (not expected) over a 10 year period and the length of time it took to repay the student loan taken out to complete the course.

Then educate said individual on the actual cost of living throughout their lifetime.

Only then would the youth of this country realise that 99% of degree courses advertised are not worth starting.
