SCBWI, Children's Publishing - A mountain of steaming bullshit?

I find myself sadly writing this, but my bullshit meter, which I have been ignoring for months, leaves me no alternative.
Having spent the last two years writing and sending out more than 20 plus children's stories to publishers and editors and agents - and indeed, it maybe simply that I and my writer's group were completely kidding ourselves as to the quality of the work I was sending out, as compared to those books that I find newly published and printed - and having not even dented the seemingly impenetrate-able wall they seem to have erected around themselves, that the publishing companies, as well as SCBWI, seem to have discovered that they can make just as much money harnessing those crowds of people who want to become writers.
The entire business of teaching "writing" to wannabe authors has become the moneymaking equivalent of the summer camps that coaches run. I don't doubt that many coaches make as much from summer camps as they do from coaching; likewise, I suspect that many underpaid editors make a tidy sum from flying into a city like Houston, staying in a hotel, telling wannabe authors what they want, handing out stickers that can then be attached to manuscripts, then flying out several thousand dollars richer, with nothing changed.
I talked this summer with Alma Flor Ada, and asked her about SCBWI; she had never even heard of it. Alma Flor, who has published more than 250 books, is busy being an author. Perhaps she got into it before it was so popular that thousands wanted to do it, and just kept her nose to the grindstone. She is either writing books, or flying around the country teaching teachers.
SCBWI, on the other hand, struck me as the New York and California crowd of publishers, editors and agents holding their noses just long enough to collect and cash their checks before flying back, happy to be away from the hinterlands.
Several editors admitted that they only did the editing and reading aspect of their job after dinner, in their own houses. Otherwise they are overly occupied with selling books that make a ton of money, and keeping happy the publishers. The Publishers struck me as very very interesting: several openly admitted they didn't read much, either when they were kids, or at present! One editor confessed to being so openly ADHD that she often strayed off topic before she finished a page. She also admitted that the old formality of sending out rejection forms was passe. If she read your stuff and she liked it, she'd contact you, otherwise, she'd throw it in the trash. So send in your work, and if you don't hear back, well, you suck. Manners?
Fuck that. Why bother. That's for old fashioned losers.
I don't guess that editors make very much. Nor do I guess that most children's writers make much, unless they find a way to be amazingly successful. The average advance for a book is 4 grand to the writer and 8 to the illustrator. You can make more money washing dishes, washing dishes is easier, probably about the same hours, has benefits, and pays weekly.
The agents there weren't interested in talking about what aspiring writers wanted to know; they wanted to brag and thump chests.
For one thing, I got a glimpse at the lizard side of book publishing, and that was worthwhile.
If you've written a decent book, or illustrated and written a book, find a publisher in China. Publish it yourself. Make the rounds with the schools. Hawk your own books. Find bookstores that will gladly carry your book yourself.
Fuck the New York Publishers and their minions.
