Interesting that the title does not suggest that the rich are sad, but rather that the materialistic (selfish?) are sad. The book review spends a lot of time trying to equate the two, but without reading the book itself I'm not sure how "materialistic" was defined and whether the book makes the same conflation. While it's tempting so think the rich are unhappy, it seems it's not actually true: richer countries are happier, and richer people within each country are happier.
