You're equating giving money to the government with contributing to society, which is not the same thing. Politicians will give your money to any cause that will get them reelected, be that vanity projects or cronies that contribute to their campaigns. That's not even the worst case, they can spend it on the military killing people, spying on the populace including you, or distributing it in some other unjust way. If you want to actually contribute to society you are better off investing it in some productive way or giving away to people in need as directly as possible. Government is a necessary evil, don't give it a dime more than what's absolutely needed as it can get out of control with little room to escape.
