It's obviously a school for the aristocracy, which emphasizes form over function. If you lose your form, it's meaningless to perform a function. A member of the elite must always look and behave like the elite. That sort of thing, I'd say. It's like the state of decadent nobility that has entirely abandoned the spirit of chivalry. Objectively speaking you might think it's a disservice to the kids, but if graduating from that school automatically helps them to be accepted into better universities and find better jobs, and generally speaking make better progress in life due to the prestige and connections, then it might not be.
