This is not about profits. This is about political correctness and not pissing off the nurses (i.e. the worker class), while fighting a common enemy (the thinkers). Also, both the MBAs and the nurses are stepping on doctors so that doctors don't get the idea that they could run the show without the former. Plus, in this model, the physician are the truly exploited ones, not just mere workers. Show me another professional business where the less educated lead the more educated. It's as if the paralegals were running the law firm.
Hospitals are full of feminist nurses (due to recent nursing school indoctrination) who hate both male and female physicians (the latter even more, because of envy). It's like marxist class warfare. I don't care if you don't see it; it's there. It's not about toeing the line, it's about disrespect and abuse, many times passive-aggressive. They abuse physicians as much as they can get away with, starting with residents. Corporate owners like it, because they want to brainwash physicians into feeling like worthless employees and losing all initiative.
