Societies, especially unprecedented experimental models, don't happen overnight they require a period of experimentation before they can develop and it's a cooperative effort.

There were numerous factions and parties in Catalonia that all had different, conflicting ideas of how things should be run.

Catalonia was never given the chance to develop before they were thrown into a civil war against an opponent that had an established military with the backing of powerful fascists including the Nazis.

According to George Orwell's account he describes a society where everyone was treated as an equal from waiters to business owners. I wish I still had my copy of Homage to Catalonia so I could provide a more detailed summary.
