Start with CONCORD-3.
I'm not saying that the US is better than every other country. I explicitly said somewhere else on this thread that there's a common critique of our outcomes that we just do detection better, and that our life expectancy outcomes aren't materially better.
What I am saying is that it's difficult to make a case that US life expectancy is materially altered by our health insurance system. You won't be able to use cancer to make that case, because the US has in fact quite good cancer outcomes. That's it: that's the whole argument.
Again, though: this repeated claim that "the uninsured aren't included in survival statistics" --- I don't know where that's coming from. It's not true.
I don’t see a source being cited other then the assumed llm.
