While I agree that there are great flaws in the US medical system, I don't think that life expectancy statistics is a good proof of them. It gives you an idea where the health care system stands because life expectancy is low in places where there is no health care system. But life expectancy is greatly increased just by public sanitation - generally, education - and vaccinations, but could be lowered by factors that have little to do with health care. American life expectancy is surely lowered by how Americans eat (no, I don't blame McDonalds who often gets the blame as an iconic brand). The kind of health insurance or lack of it, or how doctors work, cannot really decide how people eat. They try to impact but they cannot decide. Also, the US has a homicide rate that is substantially higher than in other developed countries. I won't bother myself by calculating how much that alone decreases life expectancy, but it's just an example of these other factors.
