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?
Even for software there’s still equipment needed to host it, whether that be your own or rented from AWS or Azure etc. unless you’re looking to sell it as an on prem solution(but that’s not what most customers will be expecting in the current year so probably won’t sell very well). One way around that would be to only rent the hosting as needed once you have a paying customer.
