I'd love to see an experiment where democracy was modified. People should get multiple votes, proportional not to their income or their wealth, but to the amount of taxes they paid the previous year.
There would need to be some sort of limit. E.g. nobody gets less than 1 vote nor more than 10.
But something like that would create what some call "skin in the game". Those people who pay the most money will have the most influence on government.
It's been proposed before, but never implemented AFAIK. Still, "the usual stuff isn't working". Why not some experimenting?
