On clearly unhealthy foods there should be tax. Pop, candy etc. Obviously guidelines on what qualifies would need serious consideration. Increase tax on tabacco products, booze, etc.
I think it's a pretty sad state when Southern American countries have better warning labels on shit foods than North America. Shows how much lobbying and rolling over our gov't does.
On people, no additional tax. Put it right on the products, make it not even possible for most to consume said items.
Wtf, stay away from my alcohol you puritan
