Don't kid yourself, taxes probably aren't going to significantly curtail people's eating habits. Look at how many still smoke despite the ridiculous taxes on cigarettes. Public awareness campaigns have done far, far more to curtail smoking IMO, smoking is so unhip and uncool among today's youth thanks to programs like DARE and Above the Influence, it's really pretty amazing to me how much public opinion has changed on it just in the last couple decades.
Taxes on soda are a great way for the government to bring in some money, though. That's really all this is about.
Also, how does this work for diet soda? You'd think it wouldn't be taxed as well, but I thought when I've read about these taxes before, sodas without sugar would fall under it as well, which is utter BS.
Also, this is probably going to turn into a shitstorm and be moved to P&N within the next hour.
