Based on the first link if the OP decides to go for medicine and veterinary medicine his family will be shelling out in the region of £35,000 ($58,000) a year for his courses. Holy stuff!
That's a lot but it's honestly not a lot as an American. I go to a state university which isn't as "prestigious" as the private schools. But my school costs like 7k a year for tuition and some private schools charge like 6 times as much just for tuition and their entrance requirements are usually not much different. The only real benefit I can think of most private schools compared to state schools is the networking. Which can be a big deal for some.
But it's not that all schools are too expensive. It's that people who clearly can't afford these schools choose to go to them. They're chosen degrees are normally not known for making money either. I really wish there was a push to have more people go for trade schools. Or even better would be making most jobs have a livable wage so everyone can survive.
