Well...What incentive does the govt have in lowering taxes?
If the DoJ would do their damned job and start arresting the corrupt, one incentive to lowering taxes would be their freedom.
And, if we can ever find a way to VERIFY elections, maybe through requiring that only citizens can vote and have to ID themselves to do so, we might have half a chance to vote out the ones who try to squeeze extra tax $$ from The People without our consent.
Ultimately... we can always use the nogoodnicks as shark chum...
