To be fair, how many historians etc do you need to qualify every year?
What's the point of studying something for years, getting in to dozens of thousands in student debt, potentially getting near the top of your field and then having to go work in a Starbucks because there are so few vacancies in your field?
I agree that these degrees are nice to have, but we should be honest with students in regards to the sort of lifestyle they can expect after they qualify.
