I’ve known a few in the U.S., and even worked at one. Maybe people won’t become billionaires doing this, but why wait for a complete overhaul of society to implement more of what are good ideas.
I’d also like to see more childcare co-ops, or community shared pre-k schools. Wheres the movement to build communities and pool resources around these business models in the US? In short, co-ops are the closest socialist/communist business model that’s actually implemented in the U.S., so why are more leftists not doing this?
Not every business needs to expand, though. There are quite constrained markets for very specialized goods or services. I know several B2B companies that have 10-20 employees, serve several dozens up to few hundred rather small, regional customers, and they’re perfectly happy with that.
