I'm going to be a brick wall on the whole religion part real fast. I know for a fact how many doctors, surgeons, etc. feel constantly doing all of their studies, labs, research and then some - actual learning and practicing to be the best they can be at what they're doing - doing great things by literally saving lives on a daily basis, and yet they always have to hear people thank god for the "miracle" that said loved ones are okay. No immediate common sense to thank the doctors who actually did anything for real. Nah. Just thanking the unseen and most often making a spectacle of it in the lobby, even. I have a family of several physicians is why I know this. Coupled with an oppressive enough, never-ending ball of red tape bureaucracy (from elected officials who almost always won based on THEIR religious beliefs in part), and you wind up with doctors who are that much more jaded and feel disrespected, no matter how much money they make.
Doctors and physicians are like any other people. They become conditioned after so long, even if they have hearts of pure gold and still do their best and actually do care. They still are affected by the endless lack of appreciation overall. Yeah, there are obviously those that eventually just snap or let it defeat them, and I'm sure that's why you get the ones that rather phone it in from then on. They don't last long, either, believe it or not. They get to where they seriously need help themselves, but for the reasons they reached a point of despair, they don't trust that they'll get what they are after.
