Yes, that's right. That is what it's about. I think this book he's written along with Pickett is a phenomenal accumulation of lots of research and data, and shows in such a powerful way the link between the social health of our society for everybody and economic inequality. We're familiar with what happens to people who live in poverty, in terms of the vast range of indicators about their own personal welfare. What they make the case for, I think quite convincingly, is that this spreads up the ladder, as it were.
