The problem is coming up with a solution to give us the advances (Tesla successfully made electric cars desirable, inspiring other companies to make them too, before Musk went and showed everyone how shit he is; SpaceX are the cheapest launch provider) but prevents the person who owns the company from owning the wealth it produces, and inspires those people to try

Neither Tesla nor SpaceX would exist either if Musk had not been able to take a large share of the sale of PayPal

The obvious way is preventing them from passing ownership and assets to their children, so let one person be ultra wealthy but not their successors (to keep from owning companies, government could sell off whatever shares it acquired) but good luck getting that sort of law up with billions of dollars against you
