Why haven't professors of psychiatry used their tenure to go up against the system that we’re in?

Profile of Leon Eisenberg who died last year. I've always found some of his articles seminal eg. The social construction of the human brain.

Arthur Kleinman's obituary comments are pertinent. Eisenberg "follows in the great footsteps of ... William James, because James argued powerfully for the broad range of normal experience, for our tolerance of multiple ways of being human." (WPA obituary). “He was a major voice in American medicine." (Boston Globe obituary)
