gold, page-11265

There are plenty of people trying to make a buck via these methods. It's not confined to 'gold' as seems to be your position. Below is a review of 'Rich Dad / Poor Dad' from 2002:

Where do Americans get financial advice? Merrill Lynch? CNBC? Or Robert T. Kiyosaki? If you don't know who Robert T. Kiyosaki is, well, you can find him at the top of many a best-seller list. His, is currently No. 1 on the New York Times paperback "advice" chart—a list that it's been on for an astonishing 98 weeks. Spinoffs, including Rich Dad's Guide to Investing and Rich Kid, Smart Kid, also seem to be selling.

A good chunk of what's actually in the book is self-help boilerplate. First, there's the mandatory declaration that it isn't a get-rich-quick book. Second, there's the repeated claim that "the rich" have "secrets" that led to their success and will herein be revealed. Third, the material is presented as a series of "lessons." And fourth, those lessons are positioned as being counter-intuitive revelations that effectively undercut various popular "myths." The book's back cover promises, among other things, that it will "explode the myth that you need to earn a high income to become rich."
But to generate the word-of-mouth that turns an advice book into a phenomenon you need a gimmick, and Kiyosaki's can be found in the title.

This is pretty much the ideal package: the fablelike presentation of a personal success story wrapped in the mantle of "education."
