You are right, Steve. I would go further and say that, unless I were the judge, or part of the clinical team, etc etc, I have no right to make a judgement at all, even if I had all the information.

On the other hand, I do think it legitimate to question the role of the US doctor. At the very least, there is something highly distasteful about the attitude "I could help, but will only do so if you pay me far more than my costs". He has a right to make a living, naturally, but there comes a point where that elides into something much darker.
