Well, something that the Mormons have is they tried out communism. They called it the law of consecration. They had some fun times with trying to handle being productive and redistribution and poligamous. They ultimately concluded that they weren’t ready for it yet so they went back to default capitalism with tithing and poor/fast offerings.
Tl;dr: Mormons believe in a kind of communism in heaven, and they go hungry for 2 meals (24 hrs) to remember to give generously to the poor. https://en.wikipedia.org/wiki/Law_of_consecration?wprov=sfla1
