““A pyramid scheme is illegal and is where no product or service is sold; the business exists just to bring in recruiting fees. These still pop up from time to time and are an illegal cousin to the Ponzi or Madoff scheme because of the last-man rule. The last-man rule is, if you were to extend the company’s success until the last man on earth joined the business, would it be over because they only make money from recruiting and never the sale of a product or service? If it would, this is illegal.””
