The only Socialism that has ever worked is the Israeli Kibbutz system.
Israel was a dump after WW2 and it needed to be rebuilt from scratch.
The Kibbutz system gave people a community and a place call home as they rebuilt Israel.
It worked because if they didn’t unify, the Arabs would have taken the land back from them.
The kibbutz is a commune inside a capitalist society. Every member is free to contribute to the commune or leave it. This is not socialism. Under socialism there is no simple #walkaway.
