But we have an efficient health care system, right? Well we certainly spend enough. Our per capita cost is $8,735 per person. Japan, with the highest life span on the planet spends just $3,649 per person. Canada, our next door neighbor, spends $4,642 per person. As a percentage of GDP we dole out quite a bit, 17.9 percent. Japan spends 5.9 percent of GDP. Canada, similar to the U.S. in many ways, spends significantly less then we do, 10.9 percent of GDP. Australia spends 9.1percent of its GDP.
