We have blown the concept of ownership way out of proportion. No one should be able to own things they have absolutely no connection to, like investment firms owning companies they don't work for, houses they don't live in or land they've never been to.
I like this idea, I had never thought about it this way. But it would be hard to implement, what about owning things that does not physically exist? (Like a company)
Yea it would be a pretty radical change, requiring adjustments in many areas. But I do think it's necessary, because people not being personally invested in the things they own (just financially) and profiting from other people's work is imo the big problem with our society right now.
Companies would work the same way. You can own it (make decisions and get profits) as long as you work there. Ofc you can work for multiple companies, but with reasonably restrictions (e.g. 8 companies if you work 40h/week and 5h/week/company). I also think companies should not be able to own other companies, because companies cannot be "personally" involved in anything, only people can.
