You're the essence of the problem, messieur.
What's so pessimistic about it? Whatever floats your boat, pal. If books enrich you, keep reading. Do not force everyone else to do so, though. Might be that there are other sources of enlightenment. Nature, nice chicks, long discussions, Italian restaurants etc. It's pure symbolic violence what you do right now, pal.
Easy test, though.
Speak to a random literature folk, who graduated five years ago, or so. By average, he is completely clueless. You recognize he is smart, uses much complicated buzzwords than you've ever heard of, but chances are, you do not expect him to change the world, nor get laid.
It should be obvious what's my point. If you're smart, books might help you. If you're average, books won't change it significantly and sometimes might make things much more worse, clouding your mind or hiding your ignorance behind overly complicated concepts. Accidentally, most of the world is not that smart, and it's perfectly OK.
That's why I say that books are overrated, and we should ask yourself a question whether we really get so much from them as we think we do. Chances are that some people will keep reading but others would be more happy dancing, drawing or being next Sasha Grey or Stoya, without this guilt they don't read enough books.
By the way, I don't say that there is "nothing" in books. Nothing can be something, too. However, the knowledge about Humbert Humbert and a little girl he loved, is, for me, nothing significant.
