System people in Brave New World are genetically divided into five Greek
letter categories. The best and brightest intellectuals are Alphas while the Epsilons are
the manual laborers with little need for intelligence. The other castes fill jobs
somewhere in between.
Wear grey; these are the intellectuals of society. Some examples of professions can be
World Controllers (Alpha double Plus), Directors of Hatcheries, and Wardens. Bernard, a
psychologist, is also an Alpha.
Betas: Mulberry colored; these
persons are somewhat intelligent and often work as mechanics.
Gammas: Wear green; often work as
machine minders/manipulators, butlers, and other semi-thought-provoking jobs.
Deltas: Wear khaki, helicopter
attendants, cold pressers, screw-cutters, package packers; are mass produced and have no
Epsilons: Wear black, cant
read or write, Sewage Workers, liftmen, foundry-workers, carriers, semi-morons.
