Everyone should pay their fair share of taxes and to overburden a group of people because we don't like what they do (smoke, drink, etc) or who they are (poor) not only puts an undue burden on people already suffering for our moral objectives (quit smoking, quit drinking), but allows others (non-smokers, non-drinkers) to pay less taxes than their fellow citizens. Wealthy people certainly can afford to smoke and drink all they want, it's just the poor people who aren't allowed with sin taxes. Just doesn't sit right with me.
