"Flooding of medical labor markets with mid-levels - nurses, PAs, RAs, PTs - and relaxing respective scope of practice laws"

Well, I don't have any insider knowledge, but from a healthcare consumer perspective, it sure seems like doctors have gotten scarce and NPs are doing everything these days.

I don't know how the money flows in a group practice with one doctor and everybody else is not, but I'd be curious about how it works.
