Some institutions can now charge GBP 27,000 for a degree―which may or may not be of any use!―which students will repay the rest of their lives.Twenty-seven thousand pounds, in the scheme of things, is chickenfeed. It's certainly much less than the opportunity cost of going to university for four years.
Students need to take responsibility for their own education. You've got four years, hundreds of different lecture courses open to you, and a five million book library -- it's a huge opportunity to educate yourself, but it's up to you to actually extract education from it. Many students will acquire knowledge which will be worth hundreds of thousands of pounds, or even millions, over the course of their degrees. If you haven't extracted a mere twenty-seven thousand pounds' worth, that's your own damn fault.
People who complain about not getting their money's worth out of university education are like people who go to Disneyland, sit on a bench near the entrance all day, and complain that it wasn't worth the money.
