I don't disagree that universities are horribly corrupt, extractive institutions squatting over responsibility for a system that creates an immense amount of value for society (academic research). But the claim that "a PhD is a necessary step to _specific_ well-paying and fulfilling careers" isn't incompatible with the GP comment's claim that intrinsic motivation makes people shoulder these crappy conditions, just like (eg) actors. It's pretty well-known that PhDs are, on average, _terrible_ career moves from a self-interest and financial perspective. This is common knowledge among literally everybody I've ever met who has any exposure to academia. Hell, Piled Higher and Deeper has been around for more than _20 years_; my university's paper syndicated it. Just like struggling actors, PhDs put up with low pay and bad conditions to take a shot at something they want to do, with the additional wrinkle that they're (nominally) increasing their human capital in a way that a failing actor isn't. Nothing about your comment rebuts the GP comment's claim that there's nothing unique about academia in this respect.
