The most common argument against soda taxes is the "slippery slope" -- first soda, then sugary snacks, and then they'll come for our Tostitos! -- as espoused by Americans Against Food Taxes (a group funded, of course, by Coke, Pepsi-Cola (PEP), Jack in the Box, and other likeminded food companies). "Families around here are counting pennies to get through this economy," says a sad mom in a TV spot. "So when we hear about another tax, it gets our attention. They say it's only pennies. Well, those pennies add up when you're trying to feed a family."
