I meant to say what I said: what we pay per capita for Medicare and Medicaid alone provides coverage to 100% of the population under single payer.
See chart 11-7:
Okay, still not seeing your point. I'll ignore the fact that this data is 14 years old; I'm still not seeing where it says what you think it says.
That chart lists total expenditure, which is roughly $6k per person.
Only a bit less that $3k of that is public expenditure; the rest is private.
So the medicare tax would have to, roughly, be doubled to cover everyone. I'm not seeing how the $3k public expenditure can cover $6k per capita spending.
You do understand, I hope, that EVERYONE in the U.S. pays into Medicare and Medicaid, not just the people using it, right? It's part of the withholdings on income.
ETA: Wait, I think I see the point you're trying to make now. The countries using some sort of single-payer spend less that just what we spend now on Medicare/Medicaid. That's where you're going with this, right? Got it now, thanks!
Still think that may not be a good comparison, though, because healthcare simply costs more over here. I'm not convinced just swapping to single payer will reduce those costs by over 50% (I expect it would make a significant dent, though).
