Most people have to struggle just to survive. The middle class worries about living in the right neighborhood with the right schools, so their children can have a good life. Nobody can afford to get involved in their community, or with local politics.

Noam Chomsky has written a number of interesting articles about apathy and alienation. I highly recommend The Utopia of Rules by David Graeber. Not directly about apathy in society, but related.

But sentences like "This is not an accident, people are pushed towards apathy because that serves the wealthy", without much additional clarification, might help you get perceived as some kind of conspiracy theorist.
