anybody do the whole stock market thing here?

I read this book: http://www.amazon.com/Aftershock-You...2916714&sr=8-2

Basically goes to say that we are headed for a "mega-depression" which will last 20 years once the US$ and debt bubble pops within 1-3 years time. This is the author's 2nd book after the 1st book, which was published in 2006, accurately predicted the fiasco which happened 2008-2009. Opinions?
