Direct comparisons of health statistics across nations are complex. The Commonwealth Fund, in its annual survey, "Mirror, Mirror on the Wall", compares the performance of the health systems in Australia, New Zealand, the United Kingdom, Germany, Canada and the U.S. Its 2007 study found that, although the U.S. system is the most expensive, it consistently underperforms compared to the other countries.[32] A major difference between the U.S. and the other countries in the study is that the U.S. is the only country without universal health care.
On edit: what I've read on DU about the ACA means that a larger part of the public will be "carrying" the healthcare system. If it then turns out to be a positive experience, that opens people up towards having everybody carry their part. Something I'd look for in a 2016 nominee, but I'm Crazy Left.
