> A big enough tax on fast food could probably cover it Exactly this kind of statement is what worries some about universal healthcare. I highly support single payer, universal healthcare. But statements like this undermine the cause by feeding fuel to the idea universal healthcare will inherently lead to more government intrusion into your personal decisions.
Like it or not, it's already done with cigarettes, alcohol, marijuana, gasoline, and a ton of other stuff. These type of taxes are the only way I'm in favor of government healthcare programs. Cigarettes, alcohol, and junk food directly increase medical costs, and people who indulge (and over indulge) in those things should be partly responsible for those increased costs.
They also, of course, decrease other costs due to the deaths of the beneficiaries. Is that a net win or a net loss, financially speaking?
