They are held captive, abused, and victimized by the tyrannical government and corporations. Instead of turning against them, hating their abusers, and refusing to be victimized they praise the government and support the corporations.

Stockholm syndrome, or capture–bonding, is a psychological phenomenon in which hostages express empathy and sympathy and have positive feelings toward their captors or abusers, sometimes to the point of defending them, and sometimes the feeling of love for the captor shows. These feelings are generally considered irrational in light of the danger or risk endured by the victims, who essentially mistake a lack of abuse from their captors for an act of kindness
