Right, these systems work (and are fantastic!) in large urban areas like SoCal but statistically don’t employee many health care workers. There are a large number of entire states that will never have these types of practices. What really drives the core of health care everywhere in the US are services like emergency rooms, urgent care clinics, cancer care centers, surgical services (the “shit, I have to go to a doctor/hospital things in life) - all tied to hospital and clinics which participate with the feds to survive. Added to the 163 million above are 10% of US pop that don’t have $ or insurance that wind up needing care.
