I don't mean to start an argument here, but I am unaware of *any* country that has better results -- medically speaking -- than the US.But the problem remains that the costs in the US are substantially higher than other countries that have better results.
And, as you are considering your retort, consider that countries that appear "better" than the US statistically -- in any catagory -- tend to have far more homogeneous populations than we do. Also, many of them measure "success" differently as well (i.e. infant mortality).
Remember, the rich in countries with socialized medicine fly to the US on 'medical vacations' to get the quality of care they know they won't get at home.
