Socialism will always fail, but it can work for a while like a sugar high if it has three things:
1.) an unarmed compliant population with no way to leave or take their property with them
2.) a money printer to hand out freebies
3.) a gang of ideological thugs willing to met out violence against their own people
Without those three things, it fails very fast. So I expect the sugar high of these socialist cities experiments in America to be short. But they will be followed by blame and a scramble to secure the printing press in the next national election. If they get it, the only option is to leave before they close you in. It seems outlandish now but the pendulum swings fast in fourth turnings.
