I would hope if anything like that were implemented here, the tax revenue from junk would be applied to decreasing the price of healthy options. While a bag of potatoe chips may be a ****ty snack and a sin tax of sorts would discourage its purchase, lots of american families simply can't afford lean meats, fruits, veggies and whole grains at every meal and snack time and increasing the price of cheaper alternatives to dissuade purchase will only remove food from tables where it's a struggle to provide enough calories, let alone worry about macros, sodium and additives in general.
