The author who teaches people how to make money is already $1.2 billion in debt. Robert Kiyosaki, the author of the best-selling financial popular science book *Rich Dad Poor Dad*, admits that he is using property—taking out loans secured by mortgages—and then investing the borrowed money, repeatedly rolling leverage.
