I don't feel like the author ever explained how Amazon changed Seattle and I'm not convinced Amazon did. Seattle changed over a few decades, like time has a tendency to do. Housing prices increased, as they did in San Francisco, Portland, and Vancouver. The author is (mostly vaguely) lamenting how things are different from how it used to be, but not offering much insight into why, how, and why I should care.
