This book covers some of the same material that is contained in the book, The World Is Flat. However, this book zeros in on India (the elephant) and China (the dragon) in more detail. It also spends more time reviewing the future difficulties that will need to be faced. But overall the book has an optimistic tone. Toward the end of the book it makes the case that international trade is a bargain for the USA. The book explains that for every dollar that goes overseas, $1.94 of wealth is created, and all but 33 cents of which returns to the U.S. OK, so it may be a current bargain. But is this a stable situation for the future? Somehow it seems that the current situation where China loans money to the USA so that Americans can buy their manufactured products doesn't seem to be a relationship that will last forever.
