It may be apples and oranges, but in the end they're all fruit

As health care professionals, I don't think it is our jurisdiction to determine whether someone deserves care of not. There's lots of these types of hypothetical situations that people like to pose to doctors, such as "If you had a patient who was bleeding to death and you were the only one who could save him, would you even though he's a murderer and would probably just go out and kill again if you save his life?" or whatever hoopla they can come up with. The answer, without question, is yes. It's not the doctor's job to determine what kind of person you are, or what you do. He (in an ideal setting...even though we are all subject to human biases, and that can't be avoided) is supposed to treat and care for everyone, regardless of race, class, occupation, politics, religion, what have you.

I like to think that in public health, we adopt the same attitude towards the people and the communities with which we work. It doesn't matter if it's a village of martians, if they need help and we can provide it, then we ought to do that sans prejudice.

The unfortunate reality, though, is that biases do exist. Sometimes we see certain populations as not as "hard working" as others, so we associate this with them not "deserving" the same services as those who "earned" it. Health care is for everyone. There can be better interventions and programs in place to educate and prevent people from unnecessarily straining the health care system (i.e. not taking care of themselves to begin with, waiting until an illness has reached severe stage, inappropriate overuse of ER, etc), but this goes for all populations, not just those who are vulnerable.
