Not unless it’s a pyramid scheme, in which high-level participants in the organization get rich by scamming lower-level recruits. If a business makes money mostly by recruiting people rather than mostly by selling products to the public, it’s an illegal pyramid scheme. If the company makes money also by selling products to consumers, it’s a legal MLM. It’s incredibly hard for an average person to determine whether any given MLM company meets the criteria for being a pyramid scheme.
