Instead of just making up numbers that could hypothetically mean something, take a look at what's already been linked in this thread and you'll see that's not the case.
Instead of saying "take a look at what's already been linked" either link something that refutes my point or make a clear argument that does so.
The statement was: > To play devil's advocate, looking at 5-year survival rates by country, you'd be 15-20% more likely to survive in the US after you contract cancer than in the Netherlands. YMMV.
I asked "Did you factor wealth into that?" and then backed it up with a hypothetical that shows how it could matter. I see no comments regarding whether the numbers given factor wealth in or if anyone can clearly show it doesn't matter. You want to challenge my claim that quality of healthcare is correlated with ability to pay, fine, but "look it up" isn't an argument.
We know healthcare quality and healthcare cost are correlated, e.g. http://www.pnhp.org/news/2016/july/wealthy-get-more-health-c... , I think we can intuit that ability to bear cost and wealth are correlated. Outliers aside, I don't think you're going to argue to me that a homeless man in Detroit has a chance of getting the same quality of care as Jeff Bezos.
Simpson's paradox -- how you split up those percentiles matter, the question is how much.
