How does U.S. life expectancy compare to other countries? - Peterson-Kaiser Health System Tracker

Notice how European countries rank better. But I guess that looking at data might be inconvenient. US is a rich country and yet, some of their citizens die from treatable health problems because they can’t afford treatment. From an european perspective that is wrong. I guess we just value a good healthcare for everyone over lower taxes. It is possible and it already works. But it is a choice. Americans are free to make the opposite choice, but they can say public healthcare works worse than their private ones, since we are spending less than them and living longer. The data is there.
