Brave New World - No one above no one below

In this seemingly utopian world, everyone belongs to their own social standing, so no one would cross the boundary. Alphas are the leaders, betas are the entertainers , Gammas are the servants and Epsilons are the servants. It's so harmonious that all has their role to play, and they think that they are living happily together. Things begin to change on the day when a Savage came. He can't fit in there because he feels like they are all emotionless. Basically, the citizens in this harmonic world have no feelings, and they will pop pills whenever their feelings change. These pills help supress their inner feelings, so they always react nirmally when something happen. They think the world they are living is full of peace and pleasure and they don't have to suffer pains unlike the Savages. But, The truth is most of them do not have freedom, and they have only been told that they are leading happy life. They don't have free will at all, so they don't know what they really want. However, they have been taught that they should follow all the rules since they are young. No one is rebllious so no one will challenge the system. As a result, everything is under control, the society is as stable as it could be.  Their only source of happiness is orgy, and they think monogamy is a selfish act. All of them don't have parents and they don't know what love exactly is, so they don't have desire to live their own life.
