So you arent advocating a single payer system for ALL heath care expenses. Just basic, preventive, and major medical should be covered. I have a better idea, why not tell use what medical issues you ARENT in favor of a single payer for because it seems you have covered everything in the areas you are in favor of.
You said you liver replacements for alcoholics, what about all the other medical issues caused by alcholism? What about the costs to treat a smoker with emphysema or lung cancer caused by their smoking? Maybe someone that is obese with diabetes?
EDIT: it seems I just basicly copied David's post.
