The fear of social decline or insecurity is the main driver for voters of the AfD, especially in the East.
However, the core problem is demographic rather than social. People remain nostalgic about a period where inequalities were lower than they are today. Initially, the left-wing party Die Linke took advantage of these emotions, but today perceptions have changed. Die Linke is no longer perceived as a radical opposition party, but more as part of the "system". Its electorate consists mainly of retired people, nostalgic about the East, and leftist students. Discontented people vote for the AfD.
