What if a billionaire smoker pays for your healthcare the most? I think it's completely fair for that billionaire to also mandate that you must smoke.
Then he can lobby it (and probably fail).
The system is wrong. Everybody should be paying for their own healthcare OR if there will be public healthcare, people who are at higher risk due to their own actions (like smoking) should not be covered by healthcare/pay an extra to be covered etc.
I definitely agree with you on someone shouldn't be paying for someone else's healthcare.
