It's generally very difficult to compare the cost of specific services in any meaningful way. For instance, many countries institute price controls on medication, cutting the cost of some prescriptions to 30% of what they'd cost in the US. However, some of these drugs were developed in the US based on US patent law and with the assumption of a certain amount of profit from US consumers. A price control in Canada is effectively subsidized by US consumers of a given drug, in lots of cases.

A great deal of the costs we pay come as a result of artificial scarcity of both drugs and medical services. The result of legislation, fears of malpractice, and prescription requirements mean that treating a simple sinus infection (which I can diagnose reasonably well myself) costs ~$150 or so after the doctor visit and trip to the pharmacy. There are a great many ways to attack that scarcity, but we're not really considering them (unfortunately).

Dean Kamen has a good point. The level of medical care we can provide to people is both insane and insanely expensive. High prices are rationing. What we need to do is attack the high prices that are artificially inflated.
