The willingness to entertain these different career paths starts with a disavowal of the common expectation that Ph.D. is good only for producing more Ph.D.'s. A Ph.D. is a license to be a professional thinker in the broad sense. A nonresearch career is not a failure. It is hard to underestimate the role of academic expectations and structures in making the present crisis worse for individuals and for fields. Graduate students are viewed as apprentices, not as a source of cheap labor.

The institution of tenure has created a dominant expectation about what an academic career should be. But this is not surprising given that the people who do most of the training of the next generation are the people with tenure. The traditional reaction to politics by many scientists is one of condescension and disdain. Science is objective after all. Politics is just demagoguery.
