Not that it'd be a real possibility of happening but...
Would it make sense to have a wealth limit on politicians? It doesn't really make sense to have the leaders be the ones who most benefit from the current system if we want it to change for the better of the masses. But if we made a law that was something like, "if your wealth puts you above the 70th percentile of Americans, you are not eligible for public office and are immediately removed", would that have any major downsides? Would that be better than our current system? Is that unethical in some way? Just a thought sparked by this headline.
