You might as well argue that healthy people are a drag since care in old age is so expensive.

See, I’m German. We have a solidarity based health insurance (mostly). I’m a young, reasonably healthy guy with a reasonably high income. All in all I pay 840€ every month (that’s the maximum amount), even though I cost next to nothing. And I’m okay with that.

Yes, smoking is bad and I don’t like smokers. But denying them healthcare is deeply deeply inhumane. And in Germany even unconstitutional.
