Mass automation is the only way socialism could possibly work. Once all jobs are automated, and we achieve space travel for basically unlimited resources, then socialism can work because no one has to do anything for things to work. 

And you'd still have to give perks to anyone willing to repair the automation to keep it running.

Maybe if an AI ran it for equal distribution, putting humans in charge it ensures corruption and inequality.
