You're already paying for it. The us has the highest per capita health care costs in the world. The only difference is instead of paying for it in taxes you're paying for it in increased insurance premiums and higher cost procedures and drugs. Socialized medication would actually drop the cost because the government would be able to have a stronger position in limiting the cost of care. Fats (and smokers/alcoholics) should still pay more with higher taxes though, just as many companies make them pay higher insurance premiums.
