Schiff's foresight is so staggeringly accurate it's hard to believe he wrote this book in 2006. However, he sees things exactly as they are and explains things exactly as they are. The reason finance has often been viewed as complex, is because the American public is being lied to every minute nationwide by self-serving bankers and government officials.
Schiff does the world a favor by sharing the reality of the modern U.S. economy and stock market, and it's easy to understand because his thoughts aren't crowded by lies. I am guessing he wrote this book partly to get more investors in his brokerage firm, which is actually a good thing for those investors, and partially so he could have the royal "I told you so" when the U.S. economy collapses in the imminent future–which is actually very depressing.
