Tryingthisonefornow I sympathise. It might help you to consider that your friend has joined a religious cult. A polite, sympathetic reply would suffice. You like your friend but have no interest in her new direction. A link to an MLM-critical site might assist. At the risk of drowning y'all in quotes, here's my 2p on MLMs vs legitimate businesses. Any use?
.
Bottom line at the top: "MLMs make money by exploiting the salesforce"
Legitimate companies (LCs) use salespeople to sell their products. LCs pay
their salespeople basic plus commission on sales. LCs fund training, meetings, and kick-off events. LCs supply sales materials and tools free of charge. LCs incur, therefore, some costs per salesperson. LCs do not make money on salespeople purchasing their products. LCs make sure that each salesperson has a designated area such that salespeople don't saturate the marketplace. And of course, LCs don't allow salespeople to recruit other salespeople without OK from the company!.
Multi-Level-Marketing companies (MLMs) pay no basic to Independent Business Owners (IBOs) who, purportedly, sell their products. MLMs charge IBOs for joining. MLMs then charge IBOs for - and make money from - all training, meetings, kick-off events, sales materials, demo kit and tools. Therefore rather than incur costs per salesperson, MLMs make money off each IBO. MLMs encourage IBOs to purchase their products and MLMs profit off these; MLMs use jargon to blur the distinction between IBO personal purchase and "sales". MLMs are happy that IBOs recruit new IBOs below them (as MLMs make money off each salesperson, whether they sell anything or not); due to this, there are no restrictions on IBO-saturation of an area.
Bottom line at the bottom: "MLMs make money buy exploiting the salesforce(IBOs). And I hav'nt even mentioned the cult-like mind control hooks that MLMs use! Beware!
