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.
I know there are good things that end being "open to interpretation" where there's supposed to be enough context that the reader gets the point without it being explicitly stated, but there's way more shit things trying to be good that just never had any point to make in the first place.
