It's a great book and one you should truly read before passing judgement on. It's helped me rationalize the various current political and social issues in the US a lot as I've read it.
I'll definitely add it to my list. I've generally found that a healthy study of psychology and economics, along with a deep dive into US history has given me a fairly clear picture of where things are today, how we got there and noticeable forces at work in public messaging/trends.
