Social hierarchy Division of society by rank or class.
The Berlin Wall divided the city in half with no regard to families being split or what would be available on each side of the wall. For decades a wall and guards prevented people from choosing which side they wished to live on and kept families separated. For Berlin, it also meant radically different economic systems. On the Western side, capitalism allowed for up-to-date material objects while the Eastern side was left behind by communistic policies.
