I would name this situation a revolution of writers. It’s the situation when a writer's product becomes one of a necessary need for every human being. Modern people can't feel fulfillment of their life until they don't create their informational products (in writing). That's not a caprice. That's a need, roots of which come from the depth of our existence. We've got a divine sparkle of our Creator inside, and it always will seek for a way to create something special. That's our part.
What's wrong with that in the surrounding world? Why are there so few people who are able to satisfy this need? No, my dear friends, let's not blame for our problems the publishing industry or any other mass media channels. As ever, the main reason why people don't feel themselves content even after publishing their book (or even some books) is within us. It may sound somewhat trite, but it's true. Let's better a bit change our point of view. Ask yourself if your book (or just its plot) the best for you (not for your readers even)? Be honest. Is it the best what you can write? Honesty is the way to make every your word worth living (and writing).
