You really need to apply game theory to understand how the larger medical system works. With providers, pharmaceutical industry, hospital industry, insurance, ancillary and support, just to name a few. No one is going to make a serious move unless others make a serious move. They are all linked.
I do like Germany's system, and France's system is similar. They do have single payer which is there for people who need it, but there is also private insurance. With private insurance you get better providers, better rooms, better care, etc. A lot of the tax burden is offset private pay.
I am no fan, as in zero, of single-payer healthcare/ socialized medicine.
