To me it was helpful in trying to understand the perspective from which a group derive their actions. Much like you said. Usually a good first step in dealing with interpersonal conflict is to make an attempt to understand the other perspective. The end does seem to wander a bit, but I think there's some truth in the general premise that a large group of people feel left behind (in various ways for various reasons).

David Brooks wrote a good article in the New York Times today that tries to help shift perspectives a bit to understand this. I'd highly recommend reading it.
