"Everyone works for every one else. We can't do without any one. Even Epsilons..."

This quote from Lenina demonstrates the high priority put on community and identity in the society. Social castes move from the Alphas, the most talented and beautiful people in society, to the Epsilons and Gammas, the world's menial laborers. However, each person’s conditioning causes him to feel as though they are all part of an idea economic and social system. Later in the novel, John Savage tries to point out that such a system really only benefits those who rule it, not those that are a part of it.
