Life expectancy is s bit dodgy, but infant mortality (including stillbirths, etc) is a basic stat used to measure welfare across the board. The US rates far below first world average on responsiveness and overall effectiveness, as well. You have to remember that those denied care are included in such averages - the treatment of at least a third of the population of the US rates a 0 or near 0 on the responsiveness and effectiveness scale. I'm working with a guy who is currently in his fifth year of living with a dislocated collarbone, for example. That is very, very poor "responsiveness" and "effectiveness". Try taking away their Medicare, see what they say.
