Manufactured Happiness

Published in 1932, Brave New World imagines a future where human beings are mass-produced in bottles — decanted, not born — and chemically conditioned in the embryo into rigid castes, then conditioned to love their assigned roles and kept calm by soma, a drug the World State markets as erasing every negative emotion with no hangover. The lower castes are cloned into batches of identical twins by Bokanovsky's Process, while Alphas and Betas are grown one per egg so the elite keep some individuality. The novel quietly undercuts soma's promise: taken constantly, it dulls the mind and shortens life, and John's mother Linda dies after retreating into a permanent soma-holiday.

Citizens are literally manufactured on assembly lines, their intelligence and physical traits calibrated to fit their caste. The genius of the system is that everyone is conditioned to want exactly what they have — desire itself has been engineered to match supply.
