Let them read ANYTHING they want. Even if it's comic books. So long as they are reading. As a child, I went through stacks of comic books, MAD magazine, pulp science fiction and other so-called junk. Eventually I grew bored of that and started reading adult novels, biographies and more challenging reading.
The problem is not with the schools. It's that children come home from school and do nothing but watch TV, play video games or surf YouTube.
I rarely see books in homes any more. I know some have books on devices but I so rarely see someone reading a book on a device or hard copy that I know that is not the whole answer. I began to notice few books in homes before it was possible to read books on a device. When I was growing up homes were full of books, some people had newspapers, magazines and comic books while others had bookshelves or rooms full of books as well- but nearly everyone had something around to read.
