> someone else had to get it off the ground implying what? that "workers" can't start something? Even if we imagine there's a category of people that are suited to be "starters" or "entrepreneurs" that category is still plenty numerous, easily 10-35% of the population, if not more.
Yes that is the implication. Starting something requires raising money and organizing things. Generally, at the start, only a small number of people care to do this work. And once they do it, why would they give their ownership stake away to their employees when they could just keep it for themselves?

IMO, the reason you don't see more is that us financing is quite conservative and unwilling to risk "unusual" business models.
(Similarly, finding a mortgage for shared housing requires a lot of extra work, because the mortgage brokers only like nuclear families... Even when you show up with four incomes and no kids, it's still considered risky because unusual.)
Which is to say... The smallish number of worker coops in the US has nothing to do with the rarity of magical founder people... I'll say that the folks I've known in housing and worker coops have a much higher rates creativity, grit, and organizational chops than anyone I've met from a business school. And, indeed, many of them are now run their own businesses in a wide range of endeavours.
