I'm going to repost what I've said earlier about dentistry.
This is the future of dentistry:
The ADA although it is stronger than other professional organizations CANNOT match the lobby groups that want to shove this therapist stuff. The for-profit educational lobby (DeVry, etc), the corporate dental lobby (backed by private equity on WALL ST), and the worse lobby of all: the allied health profession lobby (ie, the nurses, PAs, and FNPs, and now the little therapists) are all combining their efforts to shove this through. I particularly despise the nurse lobby. They know what they are doing is unethical.
The chains will benefit from mid-levels.
The chains will use the dentists to handle more complicated cases. The dentists wanting employment from the chains will probably have to compete with each other and see who can give the chain a lower bid for their services. The dentist that gives the lowest bid (i.e the dentist that is willing to work for the least compensation) will get the job..
