Did you and I read the same book? Most of this story is occurring in the Rust Belt[0], in Middletown, Ohio[1]. He discusses the mass Appalachian flight into Rust Belt towns and the mixing and clashing of culture.
If anything, I'm glad the author kept things largely, as the subtitle would imply, a memoir of sorts. He focuses on his family history and his life to give a face to the problem, but makes you aware that these are major problems in that community. From there you can draw your own comparison based on your experiences.
