It depends on what you mean by “superior”.
The most important thing to remember about so-called “health care systems” is that 95% of their customers (a/k/a “voters”) are either worried but not sick, or only a little sick and in need of a simple remedy. As a group, these people share two features: They can be cared for much more cheaply than they are in the US now, and they (again, as a group) do not want to pay when served.
The care of this 95% in Europe is CLEARLY superior to the US system, in cost, in outcome, and in satisfaction. This has been shown in studies over and over again, so many times as to be indisputable.
The American system excels with innovation and the care of complex, morbid illnesses. But we pay for this by overcharging most people most of the time. The people don’t like this, and they seek solutions from their politicians,
No.
We pay for bad-debt and charity-care*..."by overcharging most people most of the time."
