Noooo, it’s because we English teachers simply don’t understand why anyone wouldn’t want to read a book we love so much. I read books going “Man, I want all my kids to read this one…” And I have never taught “Lord of the Flies” because I haaaaaated it in high school. d;[/QUOTE]
Because of a strange hiccup in my schooling, I had to do that $#%$# book THREE TIMES. Once, because I foolishly picked it off a list for a project. Then, because it was part of the curriculum in a class that I effectively had to repeat. Gahhhh!
I think Reynard Ridge is right that some literature you age into. Even if you can read the words and follow the language, sometimes it’s just too far past one’s own experience as a teen.
I have always been a reader, but the most effective class for me in high school used a lot of short stories - 80-100 pages. What was nice was that we got more practice going over more different pieces, and they had a succinctness to them that made them much easier to read for both the fluent fast readers and for the less so.
I have come to appreciate that one factor of great literature and good writing is its page-turning properties - ie, if the reader has to struggle to decipher the metaphor and the reading feels labored, that’s not a sign of good writing.
I’ve also come to appreciate how audiences have changed over time, and thus what makes a ‘page-turner’ has changed over time. I took a class in college, Survey of Drama, that was derided as easy credits because there were no essays, only quizzes to prove you did the reading. We read a play a week for a year, in chronological order from the first known plays. That gave me a lot of depth of understanding of how conventions in writing came and went. Today’s kids seeing “Jaws” would find it to be ‘such a cliche’ not realizing that “Jaws” is the SOURCE of all that cliche! 
Finally, as my standard warning to all English teachers: never encourage a horse lover to read Steinbeck’s “The Red Pony” if you ever, ever want them to read Steinbeck again. In 4th freaking grade, when I was 9, the teacher suggested it, you know, because it was on The List and at my reading level but it was about horses.
