The second half of the book talks about his views on the emerging global economy. What are the forces & factors shaping the new economic model of the world. He covers a wide range of topics like globalization and its impact, Energy and its relation to global economy, Rise of some of the developing economies - China, Russia, India etc, shifts in the world demographics and how it will affect the global power equation etc. He gives a fairly detailed assessment on the above topics. He finishes off the book with his predictions on where the world economy is headed in 2030 and beyond. Alan Greenspan's support for free markets and capitalism and his belief in the self-healing power of free markets has been the anchor for all policy decisions during his long career and it comes out pretty strongly across the entire book.
Overall this was a good read and very informative book. It provides an excellent overview on high level workings on the economy and some of the key economic events of the last century. I would recommend this book for folks that are interested in knowing about economy and how it functions. If economy, capitalism is the last thing in your mind this is not your book :-(
