we use something called the “Rawlsian veil”, which avoids temporary imbalances in power from skewing the outcomes
Power imbalances are common in human society.
But many of the power imbalances which are found in human society are not at all temporary. For instance, if the player deciding didn’t vary randomly, but instead triangles always got to decide over squares, then while there might still develop a rule of law internally, its not clear what interest the triangles have in rectifying the inter-gonal situation. But we still (claim to) regard it as moral for that to happen. It seems the babyeaters are indeed in such a situation: Any adult eating the babies will never be a baby again. Further, they are almost certain to succeed in eating them, after which they will not grow big and maybe become a threat some day.
