Ive often seen individuals on the left talking about how billionares shouldnt exist etc., but when probed on how that could be accomplished the answer is usually just taxes or guillotines. I dont think either is great.
What if instead, corporations were made to be unable to be sold or owned. Initially theyre made to default to popular election for their board, and after that they can set up a charter or adopt a standard one, ratified by majority vote of their employees.
Bank collapse would probably follow, how could that be remedied? Maybe match the banks invalidated stocks with bonds?
In theory, the banks and funds in question should themselves be owned by ordinary people. As it stands, ordinary-ish people own most things anyway; even as grotesquely rich as billionares are, there’s only ~2000 of them known.
I do kind of wonder if you could have a group of companies that buy back all the shares external entities own in them. I can’t say if it’s ever happened, though.
