A program with no or a low-quality product, or with a focus on getting paid per recruit, could be an illegal pyramid scheme. However, don't let the term pyramid throw you off. It's not the shape of the organization that makes it illegal. In fact, most companies have a pyramid structure with a CEO at the top, VPs next, mid-level managers etc. What makes an illegal pyramid scheme is the lack of a quality product, or that income is earned on recruiting, not commissions from sales. 
The main attraction of the binary plan is that distributors are only required two downline recruits. Why is this a good thing? Because once you recruit more than two distributors and these excess distributors are placed below your downline, you can start earning commissions; this is a much lower recruitment requirement than other compensation plans.
They have the stay-at-home-mother meets women entrepreneur mixture working for them. What does that even mean? Means they have the practicality side of the company that is off the product and they have the sales, entrepreneur people them promoting it, too. Anyone who follows MLM knows its usually too “product practical” (see: Tupperware, Cutco) or too “opportunity-centric” (see: Herbalife).
The legal distinction between MLMs and traditional pyramid schemes has been characterized by many authorities as a legal fiction. Jurisdictions that retain a legal distinction between MLM pyramid businesses versus illegal pyramid schemes retain said distinction on two key distinguishing features: 1) that MLMs always encompass the sale of actual products/services, while traditional illegal pyramid schemes ordinarily do not (though sometimes they do), and 2) that climbing an MLM pyramid is overwhelmingly statistically improbable (especially to its highest participant levels) but not theoretically impossible, whereas climbing a traditional illegal pyramid scheme is both statistically and theoretically impossible.[citation needed]
