It seems in this chapter that the author is trying to convince us that people, especially 15-24 year olds, don't read. I got the impression it was they didn't like to read what was assigned. But that is "old" stuff. Why not work with current "new release" books for young adults? An 8th grade teacher in our area did that and the kids were excited to read them.
Thought 2--Some people just don't like to read. They can and are very capable, but they don't like to spend their leisure time reading. Maybe people are too active and spend their leisure time doing more active things. Is their really anything "wrong" with that?
