well goodwill and wisdom I suppose, I would argue that is better than regulations, self regulation trumps everything. You can't make people do anything either way. At least when they aren't concerned with their health. The problem is regulations are playing on people's fear and on the other end of the spectrum people are preying on people's lack of understanding for the sake of their own wants and needs. so I guess oaths are good as long as you hold by it.
What if all the medical professionals stopped dealing with the endless slew of bullshit and the threats of less pay and started treating the patients as real human beings. Taking their needs into account. Sure a hospital here and there would be needed for emergencies. But "A ounce of prevention is worth a pound of cure" so rather than spending millions on research and pills, why not educate everyone on well-being and nutritional balances, benefits of exercise, the links between the mind and the body and so on. Why is it almost impossible to find a good education. Either there are bureaucracies waiting to drain you or some ideologies waiting to paint you as evil. The media is no help either, rehashing old stories and bringing in more exaggerations thus widening the divide.
You and I have like views regarding the healthcare system for sure. As I said in my introduction post the healthcare system was entirely different 20+ years ago and because of all the "bullshit" as you say. I quit my job far from retirement age. Better no income from the "control group" than to go to work every day and be unhappy with the healthcare I was was forced to provide to my patients.
As for the media, that is another profession that has gone down the tubes. Instead of doing their job of accurate investigative reporting they are told what to say and they comply.
