Flood the market with doctors, just like engineers have flooded the market. That should take care of the prices really soon as doctors will have to compete for the services they provide. And remove all subsidies that artificially mask true cost... I am sure doctors would be seeing patients for $12 an hour.
Also get rid of barriers on who can prescribe medicines. You do not see that much barrier on computer programmers whose code can affect millions, or that much barrier on engineers whose design can impact millions of vehicles.
Consumers are paying artificially high prices for artificially inflated prices of doctors, including their artificially inflated medical degree costs.
There are THOUSANDS of well-trained doctors in Asia who would jump at the chance to come here, many of whom already speak English.
They can do that. Unfortunately, the doctor will be seeing you in a cardboard box in a back alley, because rent in a professional / medical building costs money. If the doctor chooses to rent, he'd be mopping the floor while listening to you because the $12/hr does not buy a janitor. He will not be using thin, sterile gloves and clean scrubs because all that takes money to buy and maintain; crude plastic gloves from Costco, intended for making a sandwich, will do. The doctor will be also on the phone as he is sticking a needle into you because the $12/hr does not buy a receptionist.
All that is possible. In fact, it was done this way, and it is done this way today. Where, you might ask? In every 3rd world country, like Zimbabwe. There they drill your teeth without novocaine (that also costs money,) and then they place the cheapest filling that falls out in a year. The doctor may not even know how to do it right - the $12/hr does not pay for much education either.
The US healthcare costs money; but it is not overpriced if you pay the doctors directly. You get exactly what you pay for. Sometimes I am even surprised how little they charge, considering their obvious expenses. The equipment alone in a small dental office costs a million dollars. Your money buys you very good care (at least today.)
There is one catch with insurances, though. Direct cash payment to the provider is 50% to 75% cheaper than what the provider has to charge the insurance. In the end it is you who pays all the overhead - and there is a lot of that.
