It's the most patriotic thing the average citizen can do. In a country where we lambast any politician who dares not wear a flag pin over their lack of patriotism, I find it insane that so many people have trouble with the idea of supporting their country and societal structure on a financial level.

Edit: Part of my response to u/combatmuffin addresses a lot of replies...

I still stand by my earlier statement in that even if the current tax code is unacceptable and the government is corrupt, the idea of paying taxes and supporting your country with some of the wealth you earned here (wherever 'here' is for anyone reading this) is a patriotic duty and one of the very few that regular citizens are beholden to. Society doesn't magically cost less to manage because someone paid less in taxes. The tax burden just invariable gets shifted even more unfavorably in terms of equity. I believe that's how the tax code has become what it is. The money being wasted in corrupt schemes should make people demand transparency, not lower taxes. We should feel the desire to engage and correct, not whine and neglect.
