Tell me this? Why don't they just restrict the number of students going to university each year? This would cost less money and fees could be kept down.
We could have a quota of places for qualifications that are needed in the country. We could close down loads of institutions offering underwater basket weaving and toenail studies.
I don't know why 50% have to go to university to get a degree that's going to cost them a fortune and not help them get a job.
Of course if people wanted to study subjects purely for interest then they could, but this would come at a price.
