Ya, I agree that's true, but at the same time the individuals choice to drink 5 pepsi's a day while washing down a Chik Fil A breakfast, Burger King lunch, and McDonald's dinner costs everyone money in various ways.
Like, I said, I feel there just needs to be a better balancing act between the two. Fortunately or unfortunately depending on you point of view, society is intertwined more so now than ever before. The day has long past where, generally, you can live in a manor you so chose and it not affect anyone else. At what point do we say that your choices are affecting my choice too much?
And, no, I'm not for a soda tax. I don't think that's a solution.
