You're the one missing the point. Of course MDs are making money by hiring AAs. Who's disputing that fact? Why else would doctors support the concept if they weren't benefiting from it? But, what's wrong with that? AAs along with CRNAs are midlevel providers. Midlevel means that someone with more training/experience is above them in a supervisory role. These are the doctors and that's the way it should be. Until a CRNA/AA can handle every situation that arises, there should be no change.
