It may not only be that either.
One of the things I have noticed, in particular about WC men, but it may be true of WC women as well, I just haven't really had much exposure to that - is that they really have a different relationship to doctors and medical advice than more middle class, and specifically university educated people.
My partner gave a very good example recently. his doctor said when he was finished the treatment he is getting now, they would talk about the choices he has for a next step. He said something along the lines of "why did she say that, she should just tell me what the best thing to do is!"
It's not really part of his way of thinking to question the recommendation of the doctor, who in this kind of patient relationship has really immense authority.
But if you are talking about recommending assisted death potentially - well, maybe if you see doctors that way, you don't really think that is something doctors should have the authority to recommend.
