I think an advantage of the way of thinking about the concepts I discussed in this post is that it might allow us to find ways to improve societies without implying that the members of the society are to blame, or should feel ashamed for, their society's problems. At the same time, they may see it as their responsibility to act to change things.
This is a little idealistic. There clearly is a deep tribalist impulse, which often prevents people from looking at their own group clearly. But maybe one way of addressing this is to get use a conceptual framework that separates social failure from collective guilt. In my perfect world, people wouldn't feel pride based on group status, but that's really a long way off.
