This book is an entertaining read with a 30,000-foot overview of state of the world along his route. Like some reviewers, I'm sure I could pick apart bits and pieces and criticize him for not talking to every faction of every political and socio-economic group in every country he visited; or the fact that he didn't provide enough of empirical data to support his claims about the over-valued dollar or other economic forecasts.
But let's be real, who wants to write a tome that covers the economic and social impact on each socioeconomic/ethnic group for every public policy decision in history in all 116 countries he visited. It's impossible. Even if you could write it, no one would read it!
This book will make you question what you're hearing in the press, and will alert you to many things you aren't hearing. This book will keep you entertained. Read it and enjoy.
