I think many people would be happy if the message in this article were actually practiced.
Unfortunately, the reality is otherwise. Midlevel providers consistently move to expand their scope of practice, so far even as to replace physicians in some fields. This is met with enthusiasm by non-clinical administrative types because it helps the bottom line. Not surprisingly, the physicians involved are alarmed because they see their ability to take care of patients eliminated. The result of this is backlash at the midlevels, even so much as to advocate getting rid of them entirely.
There does not seem to be an end in sight in the near future, except more infighting. I really only envision two scenarios playing out here: one side ultimately subverts the other forcibly, or a government regulator steps in. There is no way, with their respective egos and associated, separate, boards of licensure determining their scope of practice, a common ground will be found.
