There literally should just be a cap. Make it something ridiculous like “billionaires are not allowed to exist, so everything you earn past $999,999,999.99 is public property” and I don’t see any way how someone could disagree with this other than wanting to be a malicious parasite. That is more than enough money to buy a yacht for your yacht and is also an amount of money that cannot be legitimately obtained.
