in theory, your income taxes are supposed to funnel back down to your state (same way state taxes go back to your city). you also pay a lot of money for state income tax, property tax, tax on every gallon of gas you use, heavy taxes on booze and cigarettes, taxes on utilities, taxes on your cell phone and cable bill, excise tax if applicable, tolls, parking and speeding tickets if you get them, and fees for doing just about anything related to the government (including fighting traffic and parking tickets).
i refuse to believe taxing out of state corporations is going to make a big difference. there's already plenty there, it's just used in the least efficient way possible. this whole thing with the affiliate programs is either a really lame money grab or good lobbying by big box stores.
