I enjoy writing. Publishing... not so much. I've been lucky to work with some very talented people in the publishing world, and the print industry has allowed me to write full time.
Publishers vet books, and they do a good job keeping out the low quality. But they also miss some good quality.
Writers are essential. Readers are essential. Publishers are not.
I know dozens of authors who have had a lot of books published by New York, and they won't ever take another Big 6 contract since they've gotten a taste of the freedom, control, and money self-publishing offers.
