Seems to work OK if the majority of participants are altruists. Mind you, so does any other political system.
I would put it that Communism is classic Prey ---> Predator where the Preds fool the prey into thinking they are "equal"
Pure Royal of course is Prey ----->Predator where the Prey KNOWS its not equal
Then we have the fun where one of the Prey lands up ruling the Predators (in history this has required outside Predators to clean up)
Most democratic setups are the Predators getting bribed by Prey groups not to eat them
