Here’s the problem I have with that argument… Anyone arguing for this can go make such a company, but nobody has (or maybe few people have and it worked or didn’t and I missed the memo). It’s not a problem of large corporations or government suppression either. There are new successful small companies all the time, but they’re not “51% owned by their workers.”
So like… If you want any buy in outside of the bubble that already supports the idea, go actually do it. AFAIK, it’s not illegal, there’s nothing stopping such a company from existing other than A) nobody has sufficiently tried or B) it doesn’t actually work.
