Ah, okay. But I was getting at the doctors' reaction to this proposal. Judging by a few of the comments on the article, doctors don't agree with that proposal. But is it because they're concerned for their patients' well-being, or because they're concerned about the possible loss of income? Both are plausible reasons, but they each invite different counter-arguments. How are we supposed to know why the doctors oppose this, and how credibly should we take their argument?
