It's actually kind of refreshing to use free market lightly regulated medicine. I live in the UK where it's NHS government funded or related but travelling in Asia without insurance you can actually shop around and buy stuff - how much for a doc, how much for an xray etc. It's mostly quite cheap too. If you remove most of the regulatory barriers things work quite well. Obviously doctors and the like should pass exams for competence but I'm not sure you need to restrict it to only x people through y colleges in z country to restrict the supply. If the US said that to practice medicine and all you needed was a medical qualification from any respectable country it could drop costs like 10x I'd guess.
