The society has also found ways to eliminate things like seeing in color, bad weather, music, pain, and war. From small things like seeing in color to the large ones like eliminating war, the society is "protecting" its people by making everyone the same.

The society described in "The Giver" differs from our society in many ways. First, it is organized in small communities. Second, those communities have a strong centralized government stretching into all aspects of human life. They are communist, of course, but more than that, they reach into human souls. Not only do they assign young people specific jobs, selecting them at specific stages of their lives, but they regulate their emotions and drives. They limit their population very strictly and specifically, sometimes killing infants who fail to thrive.
