How does the zombie outbreak in The Walking Dead comics affect the world's social structure?

The zombie outbreak drastically alters the world's social structure. Governments crumble, established institutions collapse, and society devolves into a state of chaos. The survivors are forced to adapt to a new reality, forming small, often brutal, communities. Traditional hierarchies are replaced by power struggles and the need for cooperation (or ruthless competition) to survive. The emphasis shifts from order to survival.
