My wife was into one, and MLM as a concept is legit. Pampered Chef ($3 Billion company) and Avon are MLM. Of course there are tons of shady MLMs out there. What was interesting is that the WTS is SOOO much like an MLM. MLMs are structured so everyone is always recruiting. The tactics they use are so much like the Witnesses. My problem with MLMs is why don't they just sell on the store shelves if they're that great. Just like the WTS, why isn't the organization in such a way that makes people want to come (instead of recruiting) like many churches do.
