I think the trouble with the healthcare system is, it's not a "healthcare" system, it's a "sick care" system.
I don't think any doctor should have to treat any patient she doesn't want to. Why should a doctor be any different than anyone else?
My husband has had 2 heart attacks and continues to overwork himself and continues to smoke. I remember very clearly the second heart attack, when he was in such pain that even he, the toughest man in the world, admitted it was about a 15 on a scale of 10, and yet he hasn't quit smoking. I feel like saying to him, "The next godamned time you have chest pains you idiot you can fucking well call 911 yourself."
I won't say it, of course. But I DO wish he'd quit smoking. He doesn't smoke in the house and if I catch him with a smoke I chuck it away whilst cursing and threatening with the above threat about phoning 911 himself. He has actually gone so far, this past week, as to get a prescription for this anti-smoking drug, I think it's Zyban? At any rate he seems to want to quit. But he's one of these high-stress type A's, puts himself under enormous stress, works far too hard, and is, besides, married to me.
While I don't think smokers should be denied health care, or obese people, or drug addicts or alcoholics, I think there might be some benefit to everyone in graduated premiums. Maybe a non-smoking fitness type could pay lower premiums than a fat smoker?
And the various governments should really really think about really really encouraging healthy life habits rather than dealing with things when they've all gone bad?
One teeny little example: a decade or so ago the city of Montreal's public health people offered free fruit and prenatal care for low income women. They were given much good advice, encouraged to be healthy, etc., and the results were wonderful. Instead of the usual low-birth-weight babies usually seen in these women, the infants were of good weight and many of the usual problems associated with poverty, drug use and alcoholism were avoided in this group. There was going to be a very large long-term benefit to the mothers, the babies, and to "society" as a whole. But the program was scrapped because "it cost too much".
