Trenton McCarthy, chapter 7, question 6

in order to be existent or a prospering company or scheme, those schemes must follow the basic principles of economics. If not, it ultimately will fail. There really is no such thing as a get-rich-quick scheme unless we are talking about the power ball, black jack, or the stock market. Similar to a weight loss program in which it violates all types of nutrition values, the get-rich-quick scheme violates the basic principles of economics. Patience is a virtue. In the real world, there just is not such way that one can get rich fast in. They make work in the beginning but in the long run, it may not work out. Therefore, these schemes are definitely not surefire.
