Medical doctors work for an industry that bankrupts sick people for being sick and and a huge number (if not a majority) of practicing doctors can be implicated in the opioid epidemic that has killed thousands and ruined countless lives.
Ethical contracts usually just lead to more politics imo. At the end of the day, we all bow to money in one way or another (some are just willing to bow lower than others).
Maybe we should stop pretending a profession can somehow make a person better than someone else in some sort of meta/ethical way.
Addendum: Personally I wish the law were more open to allowing people to defend themselves. A few years ago I went to court to defend myself in what I was sure was a simple misunderstanding in traffic court. Halfway through my second sentence (not in the legal sense), the judge interrupted me. Then the police officer tried to explain what he put in the ticket may not have been comprehensive. The judge cut him off too and decided it was in my best interest to "learn a lesson" and found me guilty of a violation I was not guilty of. The lesson I learned was if I had paid a lawyer $500 I would have gotten an honest hearing. I don't see the ethics or standards in that.
