Universities and other education institutions don't care if there are jobs out there to fill. They only care whether there are students enough to fill their classes and campuses. If every single person in the world wanted to study nothing but fingerpainting, universities would be all too happy to furnish them with a useless four-year degree on the subject. When their fingerpainting careers failed to take off because everyone else in the world is a similarly dismal artist who doesn't want anyone else's fingerpaintings, can they sue the university for being misleading or not providing them with relevant job skills? Not at all. You came here to learn fingerpainting, and that's what you got. Payment received, service provided, exactly as described, end of story.

PS - People have tried to sue their universities for providing irrelevant degrees.
PPS - Seems like blame-shifting for a bad choice.
