Then there’s the issue of the fact that the core requirement of the PhD — developing a new idea with merit — is just hard. It takes a lot of time and work to do that in the best circumstances. I liked my department and my advisor and felt that they did the best job they could given their resources, but I was still pushed to my breaking point at times.
I remember when faculty tenure review at a major academic institution was being modified to newly include "student success activities" as part of the review process. Essentially, tenured faculty would now be assessed on how much they positively impact the lives of their students. The amount of pushback from faculty on this new criteria was insane and demonstrated the self-centeredness of most tenured faculty. The crying about "academic freedom" would make your head spin.
