The Canadian comparison had nothing to do with my comment, or the GP post to which I replied. I cited a cost, and provided the source for it. You're assuming I was in some way affirming the other conclusions of that article: I was not, and did not consider them one way or another. The GP comment was about rising administrative costs. I gave the source & amount of those costs. That was all. I otherwise agree with you: administrative costs are not the prime culprit in understanding why US costs are so high.
