The German system is not really private in that sense though. What is covered by insurance and what isn't is proscribed by law, and how much a hospital/provider can charge for it is too. And whether you are allowed to treat under insurance is organized, too, limiting the number of doctors per location. It's also more expensive than the NHS.

In reality it is a different way to administer single payer health care that leaves the doctors and hospitals (and the patients) some more freedom, but at increased cost.

From a micro perspective large organisations are often dysfunctional. You need to look at the statistical measures to compare them against other systems. And the NHS manages to give universal coverage at half the cost of the US system.
