The Federal Government sets the prices for medical care provided by Doctors who accept Medicaid and Medicare.
I am sure there are more.
Understand, I am not saying this is bad or without reason. I am just saying that is the way it is. In the U.S. there are other forces than supply and demand that set prices. We don't have a free market we have a loosely regulated and government manipulated market. Tariffs and subsidies are another way the government manipulates prices and demand.
