I think that vast majority of people read for enjoyment. If you look at the best selling books, they're almost universally "light" literature. Even the books from "serious" authors that sell well are usually their most conventional ones.

It really doesn't matter. You read what you want to and, if you enjoy it, it's great.

I just want to say, not all books are how you described literature. There are books out there that are "more true" than most non-fiction or scientific books.
