It's somewhat the opposite here. In fields like Computer Science there's more money available to pay for your education - it's typical to leave grad school without any debt, I think - than in the Humanities, where as the author pointed out it's typical to leave with huge student loan debt (which is undischargeable by bankruptcy, btw). I guess you could say that there are some fields like CS that can act as professional degrees even though they aren't officially so. And maybe it wasn't like this is Adam Smith's time, but today a large majority of working law school grads aren't working as lawyers. I think you're right - high tuition bills do make people think long and hard about going back to school. It's just that 22 year olds aren't so easily deterred from disastrous choices.
