It's interesting that so many replies function on these kind of assumptions when I am telling HN my literal experience at an Ivy League postgraduate program. I received two of the available three fellowships one could compete for. They covered less than 5% of tuition overall. Six figures of debt was the norm for my program.
Now of course, as you said, no one is forced to get a degree in humanities or what have you, but my point is that if you make expertise in these fields contingent on massive, insurmountable debt, you impoverish the culture.
