It would be nice to have more diversity in models of ownership and profit-sharing widely used in the market. Like Meta's split between voting shares and non-voting shares which lets them keep control of the company but let shareholders participate in the economic gains. There could be other models, like what if any single person could only own X shares and voting shares were only allowed to be bought by/on behalf of individuals not companies. Maybe models of ownership where the executives don't have a fiduciary responsibility to maximize profit and instead have more latitude on how they choose to run it.
