Austin Frackt has a good article up at The incidental Economist discussing this graph:

Why did the US become such an outlier; spending lots more per capita on health care but without demonstrable benefit?
A second graph shows how US longevity has not kept up with improvements noted in peer countries
Frakt touches on many of the proposed mechanisms for America’s divergence from the pack and the article is well worth a few minutes of your time.
