First off, I thought much of Dent's reasoning was sound and agree with him on many of his trends. Concur that the miss in his theory was the propensity to invest in real estate rather than equities. However, much of what he speaks of is quite reasonable, and I re-read that book in 2007 trying to get a handle on some demographic waves. I'm interested to see his new book and will probably purchase it, if only to see updates on the demographic trends. Few points to consider: 1. There was a terrible error made in 2006 by the republican party when they alienated the hispanic population by suddenly becoming anti-illegal alien amnesty. Who would have filled those tract homes being built some of which are now NEVER going to be occupied? The army of illegals nationalized and brought into the fold as tax-paying citizens and resident aliens. Only difference was that they could circumvent paying for services due to their illegal status. Now, many of these folks are gone - back home to their own countries where their dollars have been converted to local currency and aren't easily returning. 2. Agree with the idea that things are proceeding along faster than expected. I don't think you can use these concepts for exact (even within 1-2 year) timing, as too many variables exist, including external effects. But the fundamental cycle remains the same, and you can use this information to profit. 3. Finally, we could see dow 40,000. Just don't be surprised if EUR/USD is trading 4.0. Everything is relative, you know.
