Irrelevant. $ per $ != morality.
Where in that quote did I mention money? That is your assumption that its only about money. They cannot undo psychological damage, physical damage, etc. There is no real way for someone to be fully responsible for their actions. People are able to cause a lot more harm in a society than they are able to fix.
None of your solutions proposed involve any sort of reality - just short sighted idealism.
Look, I'll help you out. If you believe that PA/NPs should be allowed to practice medicine.. that is something I can agree with in a limited context. I believe that there should be a better path for high performing nurses/PAs to take on higher levels of leadership/responsibility in medicine.
But what is going on now is not about morals, its a simple power play. Nurses/PAs could/should be advocating for better training (comparable to medical training) instead of advocating for more power. Once they are well trained, why would anyone want to avoid utilizing their services/training and give them more power. Giving them power would be a moot point. But that isn't what is happening. They are trying to shoehorn their way into medicine while trying to avoid doing the same level of training. I don't think its "moral" or "fair" to expect the same level of responsibility/compensation as someone else without doing a comparable level of preparation.
If nurses/PAs were intent on being better providers of medicine and elevating themselves, their boards/organizations would be working to improve the rigor of their training, the selectivity, etc. They could be working with ACGME/AOA to help get their best into residencies.
At the end of the day, you do not want to dilute a product/service. Cheaper and cheaper products with lower quality is unsustainable as a model. Instead, keeping the price while improving the quality is sustainable (its what the longest running companies do, in general).
Instead of adding medical providers with lower levels of training in terms of rigor/hours, why not create programs that are comparable to medical training or expand medical training in fields that could use it in areas that could use it. Or just add spots in general. Nurses/PAs shouldn't be forced to train in rural areas but they should be willing to compete more for more desirable locations and fields - just like med students do.
If I were a residency PD, I would gladly take a 15 year PA to train who has great references from people they've worked with and is a proven quantity and proven experience. They should be very low risk for attrition. Ditto for the best nurses/NPs since they've already gotten their feet wet. If they are lacking some science background, I don't see why residencies can't have electives for them to shore up their science knowledge before taking the licensing exams.
This method would address qualms about the lack of training hours or the lack of rigor (due to accusations of management type courses in mid level training like DNP/NP programs).
This is just an idea but, in my opinion, a lot more realistic than using a specious moral argument.
