Taxes are evil. Taxes are theft.

Or not.

You're not going to change behavior by moralizing to people who consider what you think is moral to in fact be immoral, or who at least are amoral about the whole manner as corporations tend to be. Since we can't seem to agree on the moral issues of taxes, all that's left is the reality of law, and the incentives of the law. It's posturing to think we can solve the matter by any other means than top-down legislation and enforcement, if indeed there is a problem to solve. (Corporations and individuals both have many arguments for why they are paying enough taxes already thank you.)
