"Tribal engineering is the idea that culture transmits values and memes to its young in order to inculcate them with the idea that dying for their culture is acceptable."
Collectivism keeps individuals from truly being themselves, it pushes them away from embracing their true identity, and self-actualization. One of the most common forms of collectivism is tribalism, which usually puts the group's needs ahead of the individuals. And, when a culture has been engineered to believe that is acceptable, they will cheer for it.
