What do you mean by the word envy? Do you think it's a moral problem? Are you sure there's no plausible interpretation of this person's words that doesn't (or shouldn't*) sound envious?
What I mean is that it sounds as though the GP is resentful of others he feels (rightly in many cases) have had an advantage over him or her. I don't think it's a particular moral failing, but I also don't think, on the balance of probabilities, that there's another reasonable explanation.
So, envy is not conceptually immoral on your view. It's perhaps a positivist's type of resentment, I take it. If that's the case, then I think I understand where you are coming from.
