Zetta Elliott makes some great points re people of color in books and as authors.
Without in any way diminishing the very real problem of the white worldview of children's book publishing, I am struck by how often and widely charges of non-representation ("why aren't there more _____ in children's books?" "where are the books for ____ children?") are made of children's and YA literature. Books for and about boys. Books that show children in non-traditional families. Books that show children in traditional families, attending church. Middle-class black people. Girls who don't like pink.
The thinking goes that if there were more books about and for _____, more kids who are the same _____ would read. I wonder. Although I do believe that readers, at least in part, read for "the shock of recognition" Richard Peck talks about, I'm not sure that translates to wanting to read books "about people like me." It's more about being able to see yourself in circumstances unlike your own. To take the argument to its absurd conclusion, the belief that books should reflect their readers' circumstances means we could all give up reading and just look in the mirror.
But the concern here isn't so much with readers but with nonreaders. Do you remember the scandal of a few years ago with those Freakonomics guys, claiming that an enjoyment of reading was genetic? That kids didn't read because their parents read to them twenty minutes a day, they did so because their parents, as readers, were more likely to read to them twenty minutes a day? This is a little too mechanistic for me but I don't discount it completely. The pursuit of a more varied literary universe is an unalloyed wonderful thing--for readers. But I don't know that it will swell the ranks.
