So perhaps there aren’t that many workers cöoperatives because most working class individuals are simply unfit for leadership positions.

I mean you can’t really expect someone whose job is to wait tables to know how to properly run a restaurant. It takes someone who understands systems and most people don’t.

Huh? How does being a cooperative preclude those businesses from having capable people in leadership positions? The only difference between a regular business and a coop is that generally coops will vote on who is in that leadership position, and they don't over-value that leadership position, unlike most CEO's which take an unjustifiable amount of money for the amount of actual work they contribute to the business.

How does North Korea, an authoritarian and decidedly not socialistic state (the workers do not own the factories in North Korea, the State does, which is bad) relate to any of this?

An unfortunate amount of the poor in the USA become homeless, which takes away access to cars and fridges.
