IMO, speaking from the perspective of an ecology doctorate, while PhDs have much to contribute outside of academia, the training is laser focused on that route, to the detriment of students and funders (which is, generally speaking, society/taxpayers). The reality is more PhDs are minted than exist professorships, yet many advisors wish you to be their academic offspring, not just continuing in research but in their line of research. This dynamic was far more the cause of mental health issues than the work being “hard”, which checks out since there are innumerable other forms of hard and harder work.
