How do pyramid schemes differ from direct sales?

The vast majority of consultants, even successful ones, make the majority of their money in direct sales through selling the company’s product to customers and earning a commission from those sales. There is huge benefit in recruiting new members to their team, though they do not make money just from the recruiting process itself. They DO earn commission on the sales of their recruits, however. And they are earning that money by training their recruits on how to run their business productively, keeping them engaged, informing them of news from the company, and many other duties and responsibilities.
