This is an excellent review of how the new economy works. For centuries, economies have focused on the tangible economy, but we are rapidly shifting to an intangible economy especially in the Western economies. While our economy will never be even close to entirely intangible products, there is less and less need to produce tangible products, other than consumables. Just think about your TV. You probably spend more on your cable service in a year than you spent on your TV.
This book is well written and easy to understand without a degree in economics. If you want to understand why the biggest companies in the US don't produce anything you can actually hold, read this book. You'll also gain a appreciation of why theft of intellectual property should be a national concern, even for those who primarily produce tangible products.
