Basically every bit of the current system, from how much people are paid to how a hospital looks like, is a side effect of the way we pay for healthcare, and the way we decide which provider to select. So we cannot just wave a magic wand and get the German system, as a whole lot of capital decisions are now just straight out wrong.
We see similar things in education. People wonder how many European systems are cheaper than US universities: Well, it's very easy to see once you attend a university in Spain and then one in the US. The shape of the university, from facilities to salaries to class sizes, make them look like completely different organisms, even though 18 year olds come in from one side and come out with degrees in the other. And note that this is also connected to healthcare: How many doctors do we train, or bring in from other countries? How many years do they spend training, and how much debt do they incur getting training? How much are they going to ask in pay just to handle that debt?
Changing the US system is a very good idea, but the changes would be very traumatic to most people working for the system, or invested in the system. All of them would lobby against changes that make their lives worse, and therefore makes legislature that makes the change happen very difficult to pass.
