Realistically, if you have 300M, you and your direct family are settled for life. So, I want to propose 1B cap on net worth, if its more than that for 12 months straight, surplus goes to government, if your net worth is down after that, government obliges to return it partially to make it to 1B.
People, who are eager building things and innovating, will keep building regardless, power hungry will try to find other ways to enrich themselves, but eventually they will give up (e.g. having 10 kids, each with 1B net worth)
