This book has three parts. In the first part, the author uses government data and charts to show how the consumer is building up debt at a rapid pace. The author believes that this can not go on forever, and eventually the consumer will have to slow his spending, which will dramatically slow the economy. If you don't believe this conclusion, and the data that supports it, then the rest of the book is meaningless.
The second part of the book states that as the economy slows, the stock market will drop. The author uses several methods to estimate how far the market will drop, including Yale Professor Irving Fisher's formula that uses dividends for deriving real market value.
The third part gives conservative savings calculations for retirement. These calculations differ from those in most books because they don't include stock market gains, and they assume that Social Security retirement benefits in the future will be delayed until age 70.
I liked this book a lot because it backed up all its conclusions with data; sometimes almost too much data to digest. But the inclusion of this data, the focus on consumer spending, and the willingness of the author to extrapolate as to when the consumer debt limit will be reached, separates it from other books predicting generic economic problems `some time in the future'.
I was surprised to read the very negative rating of this book by an earlier reviewer. The fact that the author graduated from Cleveland State University in engineering and was a former GE Engineering Manager is right near the front of the book, so I don't understand the surprise. This book is very data oriented, and the author's earlier books on Six Sigma seem to validate that he has expertise in data analysis. As for not suggesting selling stocks short, which has a risk theoretically greater than the amount invested; this is consistent with the author's apparent conservative approach for riding out the first half of the predicted depression. I, personally, would consider gold more strongly as an option; but again, the author is very conservative.
