And what is 'efficient'? I think a major component of a well functioning healthcare system is that it's equitable. Our problem with healthcare is driven by the generalized problem of 'economization.' A rich person doesn't have some intrinsic quality that makes them more deserving of quality healthcare.
A healthcare system which is extremely efficient at treating the rich and letting the poor die isn't really what I'm looking for. Efficiency and equality must be balanced. What I'd say is that the US is pretty terrible at both and that's sad.
>Instead of wasting time with examples that don't go for the core of your stance, can you share what would change your mind in the general?
Some evidence that shows that mostly private healthcare systems generally function better than mostly public ones or some evidence that healthcare regulation in the US has led to worse outcomes and not better ones would at least give me a jumping point. But I'd also ask you to answer your own question here.
