I wonder if they factored in used book sales? Also, what about books online?

I am thankful all of my kids love to read, but my youngest grandson is allowed to play too many video games, imo. (I wouldn't let any kids play them until they are much older.) The saving grace is he gets plenty of outside activity, music, AND a book read to him at night, every night, plus he sees his mom and the rest of us with books all of the time AND, at 4, he wants to read, so we're working on that, too.

From what I've heard recently about schools, graduates and their skills, etc. in the UK, I don't think it is just America which may have a problem.
