The temptation here is to cite his more recent, post-crash work ("Fixing Global Finance"), but if you want a soup-to-nuts explanation of why I believe in globalization's overwhelmingly positive impact on the world in recent decades, this 2004 book is still the ultimate primer in my mind--worth the long slow read. It's like taking an international economics course. So best to start here and then trying the more complex recent volume.
Whenever I get asked, "What's the single best book I can read on the global economy and globalization?" I always cite this book and will until probably Wolf dethrones it himself.
I had the distinct pleasure of meeting Wolf at a regional Davos meeting (off the coast of Australia). He saw me give the brief and we had dinner following, with my old friend Minxin Pei. He is as charming and fascinating and intelligent in person as he appears in print.
