We once read a book called "Feed" in high school - a ham fisted anti-capitalist book. Wherein citizens are 100% connected to an internet like service that only exists to sell them products. 90% of the class couldnt get it. Even when the teacher sat down and explained the entire plot of the book they still couldnt wrap their head around it.
It's mostly about how allowing blood feuds to decide your life is a really, really bad idea. Like, don't let some kind of vague enmity destroy your life. The reason some of the adults in the story allowed Romeo and Juliet to get married was because they thought it might end the feud, but the reaction was more violent than they expected.
