This is the issue with how this whole thing is framed.
Of course the university doesn't owe grad students anything besides an education.
But, being a grad student need not involve any teaching or professor research support. That's labor. It's customary labor that may be exchanged for education, but it is indeed an exchange of value for labor and subject to everything that entails.
Source: got a real grad degree without any of that BS just paid tuition (partially via my employers tuition reimbursement:)
Lobotomy, electroshock and castration are historic treatments for various extreme mental disorders that were, probably mistakenly, considered necessary evils lacking other treatments.
These days prozac, benzos and lithium fall into a similar category.
This is very true for me. Same for a lot of history museums, which are full of historic arts and crafts.
Like, some native art is just old craft, not actually good art to me, but some ancient cultures had a wild perspective and the art matches.
