If you're wealthy, the US health care system is so good that not only does it outdo Europe's system at handling heart disease and cancer, but it does so much better than Europe's that the effect is evident from mortality statistics even though 75MM people in the US make less than $22,000/yr. At the same time, you're saying that regardless of the fact that US hospitals are required by law to treat indigent patients regardless of cost, enough people receive so little care that they bias the mortality statistics.

This seems like an extraordinary claim.

I am not an apologist for the US health care system, as a cursory look at HNSearch will show you. But I don't think the problem is that people don't get care in the US; it is, as policy wonks will tell you, better (from a health care perspective) to be homeless in 2012 than it was to be President in 1955. The problem is that the US health care system routinely bankrupts patients.
