The participation on this site rivals the sites that are restricted to practicing doctors. Good job.
You bring up many great topics. I'll try to address as many as I can. Here goes.
MISREPRESENTION BY NON DOCTORS: I agree that this is a particularly abhorrent practice. As a resident, we encountered one of the most egregious examples. I can share the essence without revealing identifying info by disguising the details a bit. Imagine a nurse-midwife who, by rule, is required to identify herself as such. So she goes and gets herself an correspondence course PhD in some bogus field like Underwater Basket Weaving or whatever. Easy enough to do. So guess what? Now, she walks into the patient rooms in her long white coat and tells the patients she is Dr. so-and-so. Technically correct, although her doctorate has nothing to do with the practice of medicine. Compound this with a hefty percentage of the patients being Spanish-speaking only and you have a classic situation of egregious misrepresentation. Anyway, regardless of what side you are on in the NP/MD debate, there is no excuse for a NP/PA to be able to call himself/herself a doctor.
VOLUNTARY PERSUASION vs FORCE:
OK, so putting that aside, one of you came up with a great example of the electrician doing wiring in the house and how people don't know the wiring is faulty until the house burns down. Very valid example. I also read where one of you advocated diligent education of the public as an approach. Very good. In my opinion, this is certainly more palatable ethically than clamoring for the use of FORCE to block/curb NP's.
Basically the new question becomes: At what point, if any, can we tell a grown adult patient that because something is so much "for your own good" and because "you are too stupid of a layperson to make an informed decision" that we can force our policy down your throat rather than let you make up your own mind.
An example of using voluntary persuasion would be "Hey, you should know, that this is the danger you face if you allow yourself to be cared for by a NP/PA instead of one of us MD's. Here are a list of cases where a patient was mismanaged by a NP/PA and didn't know about it until years later, an underlying problem was revealed which by then caused great irreversible damage. So I urge you to think twice before you agree to be seen by the NP/PA for your complex health problem". The reason this approach is ethical because it has automatic built-in checks and balances. If in fact, NP/PA's are dangerous in whatever capacity you are citing, then logic dictates, you should easily be able to find examples. Nobody has to make a case that getting drunk and jumping out windows is a bad idea. The Journal of YouTube Stupidity attests to that. If however, this is not for patient protection, but just a case of a more elite ranked individual trying to protect his own interests, his own turf, from lower-cost competition, it will fall flat on its face for lack of any evidence.
In other words, using your great electrician example, one should be able to say "Hey, you think you're saving money using the NP electrician. Well, did you know that last year alone, there were 1000 fatal house fires that resulted from faulty wiring approved by a mid-level electrician! Here is the data. Now are your family's lives really worth saving a few bucks?"
However, if the truth of the matter is that in the past 5 years, there were only 2 fatal house fires from faulty wiring done by mid-level electricians, you could still try to argue it as "Even though it was only 2 fires, what if it were YOUR family that died?", and it might be convincing to some patients (who will then choose to see MD only), and less convincing to others (who will shrug and say, OK I've been warned, but it's not enough to make me avoid the NP/PA).
This use of persuasion rather than force is still the preferred tactic from a moral approach.
Here are some more reasons why, again using your electrician example.
Let's say your best argument is that the MD electrician always flawlessly wires the house while the NP electrician makes an error that results in a fatal fire 10% of the time. If this were the case, you would not need to do much education. The truth would speak for itself. Word would eventually get around quite emphatically and any person with half a brain would be quite insistent to have their house wired by MD only. If this were the case, we would not be even having this debate, because in that case, it would be common knowledge that NP's are vastly inferior to MD's and nobody would gamble any significant healthcare into their hands.
But what if MD electricians were not themselves perfect and their wiring results in 2 fires per 100,000 while NP electricians' wiring results in 5 fires per 100,000? How significant is that difference?
What if the overwhelming majority of these fires were not fatal, but say caused $20000 worth of damage to the house?
What if it costs $10,000 to have your wiring done by MD-level and it costs $3000 to have your wiring done by NP-levels?
What if some companies offered wiring done by NP-levels, but always with a final sign-off by a supervising MD-level?
One of you said it well in that this issue is not cut and dried. It certainly isn't.
Reversing roles and speaking for myself as a patient, I would gladly pay a $5000 deductible to have my angioplasty done by a MD rather than have a free one done by a NP. But if I had a ingrown toenail that needed I&D, would I pay $400 for the MD vs free by the NP? Not sure.
PREACHING TO THE CHOIR: One of you pointed out that the majority of people here have their minds made up on this issue and agree that NP/PA's must be stopped or drastically limited in their scope. Fine. What can you do then? The classic fallacious answer is "WRITE YOUR CONGRESSMAN". "Be an activist to make sure the right people are elected". Do a reality check. Of the 1000's of problems in this country (war, senseless war on marijuana, predatory lawsuits, corporate welfare and bailouts, incarceration of minorities, corruption in government,illiteracy), how many have been resolved satisfactorily by writing congressmen, activism or voting? 99%? 75%? How about < 5%?
Ask yourself of the following which does the most to influence lawmaker actions? Really.
A: Voting
B: Petitions/Activism
C: Letter writing to politicians
or D: Multimillion dollar lobbying by special interests.
OK. It's late and I realize that I could be guilty of being one of those people who point out all the problems without proposing a solution. If we were slaves on a plantation back in the day and I tried to convince you all that the system of slavery is unjust and we need to open our eyes to how wrong it is, you could very justifiably throw back at me "Well, suppose we agree with you that it's wrong. What do we do about it?" my unsatisfying answer is "I don't know. I don't have a fast/powerful solution, but I do believe it STARTS with realizing the nature of the problem is the system itself." Instead of fighting if we should vote for slavemaster A or slavemaster B, perhaps we can begin by examining whether the slavery system is fundamentally corrupt?
Furthermore, although there is no fast/easy GLOBAL solution, I would challenge that there is a solution for each and every one of you on an individual level and those solutions differ from person to person. For one of you it might very well to explore your choice of specialty. For another of you who had her heart set on primary care, it might be exploring the concept of concierge medicine. For another of you, it might be, chill out, accept it for what it is and plan on having great hobbies and family life and seeing your doctor job as a stable way to clock in/clock out and pay the bills.
In any case, I may be at a disadvantage in my arguments because honestly, I love my work. Fundamentally nothing beats the opportunity to change people's lives by the proper manipulation of medicine, surgery and the art of medicine. But my heart still weeps for my colleagues who have grown coldly bitter as they stood by, watching their profession becoming increasingly bureaucratized and overtaken by insurance companies and politicians. Best wishes to all of you. The fact that are engaging in discussion proves that you care.
TL/DR:
1. Persuading the public is a more moral approach than using legal force to disempower lower level competition.
2. Politicians are human beings and as such, will have their own best interests first, so effectively persuading them requires that you have millions to lobby them with
