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?
Your questions at the end are what distinguish this from a co op.
Im not saying i have an answer for every case, but a co op has strictly one vote per employee.
I think itd be okay to build on top of that and let co-ops of more than 2 people set up some sort of charter or constitution that requires periodic re ratification.
3 is the minimum amt of employees that makes sense imo.
