Books like Lord of the Flies, 1984, and Fahrenheit 451, which aren't even difficult books to read- a middle schooler can read them and understand the contents just fine, since they're written in a style that's easily digestible to a modern English speaker (especially Fahrenheit 451), and the themes aren't especially esoteric. I'm not saying they're bad books, or that they're dumb books-a lot still goes into the writing and nuances-merely that they were written to be easily digestible to the average reader, and people shouldn't feel so highly for having read them.
Nothing is special about having read Shakespeare, too; again, they're common reads for middle-high school students, and the reason they are so highly-regarded and influential in the first place is because they were the early-modern English equivalent of Star Wars. They were literally the start of pop-culture, not high art.
