Uniformity is the defining feature. There is only one language, and all ethnic groups have been eugenically merged into one race, "The Family." It is so genetically uniform that no transplants are rejected. There are only four personal names for men ("Bob", "Jesus", "Karl", and "Li") and four for women ("Anna", "Mary", "Peace", and "Yin"). Instead of surnames, individuals are distinguished by a nine-character alphanumeric code, their ""nameber"" (a neologism from "name" and "number"), such as "WL35S7497". Everyone eats "totalcakes," drinks "cokes," wears exactly the same thing, and is satisfied every day.
