I think people who don't take their health seriously and refuse to take steps to improve their health issues should be required to pay at least triple the health care premiums that people who take care of themselves do.
These people the ones who will ultimately be burdening the health care system with their self-imposed medical issues. Why should responsible people have to pay for that?
This is already partly true.
First, if you have private insurance and have any problem, including treatable and preventable problems e.g., smoking, obesity (usually), you already pay higher insurance.
Second, employers can refuse to higher you if it will raise the group rate.
Third, Alabama is gonna impose a higher insurance rate for their obese employees.
