Actually, this is something that I've given a lot of thought to over the years. I believe that if an income tax is required, it's only fair that large tax payers have a greater say in what happens in politics... And that there are certain choices that you make in life that should also make your vote count for more.
For instance, I've always thought that every citizen should have 1 vote. Even if they pay nothing in taxes. They would get an additional vote for every $10,000 in federal taxes they pay. If they were in the military, they get an additional vote for every year they served in active duty. And another vote for every combat tour they served.

Wasn't there a system very much like that years ago --- until they broke up the Round Table and severed the bowstrings???
