Who knew that medicine and library science were the same thing? Come to think of it, I bet librarians could replace lawyers, too. Just need to teach them to shout "objection" and be jerks in the coffee room, right?
ISTM that many of the complaints of fat people echo those of elderly people. The medical community has somewhat responded to those by creating the specialization of geriatric medicine. End-of-life care, especially for elderly patients in pain, still sucks, but they're trying to do better. When fat people have better politics, perhaps they'll be able to pressure the doctors into providing less egregiously poor care for them as well.
Lets not pretend that it is not going on. Lets face the facts. Many people (if not most) are not motivated primarily by their need to make the world a better place for everyone else. We are too primitive for that. I'd argue we aren't even programmed for that yet. In a world where people think it is acceptable for people to starve if they can't or won't work, it is too much to think that our doctors, lawyers, and corporate executives are a different breed or species.
Sorry I have tremendous respect for our doctors as I have for our soldiers but that doesn't mean everyone who goes in to medical school or military training went in with perfectly altruistic purposes.
