This is why I cite problems with Canada, UK, Hawaii, Massachusetts, Tennessee, Medicare, Medicaid, et all as real world problems with government run care.

Most of those are distortions in your current faulty system.

You say you cite potential problems in other systems. What about benefits? Surely value is derived from the balance between benefits and problems. If you only ever allow the problems you'll end up with the current system that most stakeholders agree needs reform. FWIW I'd recommend you add the Netherlands and Scandinavian countries to your list too.

I look at these systems and see bloated bureaucracy, rationing and a subservient populace for whose health care decisions are made by an outside force.

You're looking at an image you have created for yourself rather than what people in that situation may actually say. If you look, you'll find that people who have these systems are generally pretty pleased- possibly more pleased than people in the US. People in the best of them have an awful lot to be pleased about. If you look at this you may see potential elements or mechanisms that resolve your fears. If the democrats have any sense they'll start producing this sort of data, though it's risky since people who are accustomed to believing they have the best may blame the messenger.
