If they are so rent-burdened, they should consider living with a roommate, or perhaps 2 or 3 roommates. Then they would be more easily able to afford basic necessities.
I can’t speak to GP’s situation, but TFA makes clear that the university grad student housing available at UCSC in this specific real-world case is in fact not sufficient for the graduate students to afford such a living situation on their stipends.
And what do you know, the rents are still high. At what point do we realize that an administrator making 600k a year off the backs of people toiling long hours in labs to bring in grant money for the school and coming home to live in tenement conditions isn't the fault of the students, but the administrators making half a million dollars a year? Quite a hill to die on.
An administrator is paid that much because that is how much value they provide to the university system. A graduate student provides minimal value, in fact barely above replacement level. That’s why they are a student.
Are you a grad student? And you never took an economics course? This is pretty basic material.
