I think it is far to keep working if you love what you are doing. To filter, there should be an absolute cap on wealth at a few hundred million dollars. This would eliminate the incentive to manipulate politics in favour of yourself, but if you want to keep working you should be doing it for society via charity or taxes on anything additional that is earned.

Have a nice ceremony and present a medal for winning capitalism.

One million dollars and not a penny more. Enough for most people to live comfortably, but not enough to buy governments, or for the upper classes to never need to work again to maintain their lifestyle and privilege.

No human being needs or deserves a hundred million dollars.
