Is comparing the per capita cost of healthcare to that of U.S. really fair, especially when advocating adopting certain elements of the "Amish system"? The U.S. is pretty the worst example of keeping costs down; other first world healthcare systems cost much less than the U.S.'s with similar or better outcomes. I suppose it's reasonable because the Amish live in the U.S. but I guess the question is do the Amish do particularly well or does the U.S. just generally do particularly poorly? I do think there are some interesting insights in the article though. Edit: another observation is that the author is probably not putting enough emphasis on the additional cost of end-of-life care (though he does mention it), especially if he's correct that the Amish tend not to spend as much on prolonging the life of older people.
