I found this book very useful in understanding the role a special kind of transnational elite is playing in early 21st century globalization. As shallow and superficial as their lives may seem, these young globetrotters are in fact important players in quietly, in the shadows, building a new planetary civilization and monoculture.
I give this book 4 stars instead of 5 only because I would have liked to have seen a more detailed and impartial sociological treatment. Stalnaker is clearly writing for a marketing audience, probably as a hub player himself, rather than for a more general readership. This is currently the only such book I am aware of that deals with the hub elite, but I hope more studies (with a few more pages) follow this work.
Interesting for students of globalization, this is also a useful book for people considering going expatriate, and developing an overseas life and work strategy.
