I might modify a few of these, but no fundamental disagreements. However WRT #1, we must find substantial cost reductions/efficiencies vs our present systems before increasing taxes to cover costs (then I'm OK with paying more). To just institutionalize our current system at 50-100% higher cost than other countries isn't something we can or should afford.
Interesting that we have developed countries (many with mature systems & results) all over the world to benchmark, even some who started from private systems like ours (Switzerland the closest from what I've read). You would think we could look at all the others and model the best system possible, I believe that's exactly what Taiwan did. [Yes, I realize why it's not so easy...]
I've linked to it before and others reference it above, viewing
Sick Around The World | FRONTLINE | PBS is 60 minutes very well spent for reference.
I still wish some of the posters here who claim the US has the best healthcare would provide something concrete to support the claim. I wish it was true, but I can't see the evidence to support it...
