Unless your extra generous contributions are in the 10's of thousands, hundreds of thousands, or millions of dollars per year (depending on which government you're referring to - local, state, fed), I can assure you, whatever money you send to whatever government is not significant enough to make any difference. You're far better off sending that money directly to vetted non-profits that do the things you think your area needs more of.

Not to mention, governments like the US fed will just poof new money out of thin air if they can't afford something anyway.

And... when it comes to tax law, you had better follow the letter not the spirit, otherwise you risk an unpleasant visit from your local tax auditor. Your interpretation of the spirit of the law won't get you out of their crosshairs.
