I am an avid listener. I listen between 75-100 hours per month on my iPhone: 60% fiction to 40% non-fiction.
In the demographic Cliff, Dent make a reasoned, well supported argument for his predictions. The first third of the book is very slow because he spends a great deal of time convincing you of his solid record in past predictions -- of course they have worked out well or why would he write another book?
That sarcasm aside, he makes a very convincing argument and it dovetails with other books like "The Next 100 years" and Freakonomics. I think this is a must read -- think it over, his argument does make common sense.
I agree with the others about the performance, it is slow, monotone and boring. But if you can look past that there is a TON of great information here. This is the best real estate investing book I've read in a long time. For once I didn't feel like I wasted my time on another sales pitch from some rich dad.
