I heard something on the radio, forget where, where a caller wanted to eliminate all taxation save a national property tax...if you didn't pay any tax, you don't get to vote, period.
Kinda like that idea, no skin in the game, no voice! Certainly would have a built in bias towards responsible republican government, being accountable to those with the most to lose if you screw with them too much!
But of course such a mediating measure on the undesirable side effects of democracy will never pass as long as demonrats walk among us...
