Now that I have a bit more time to type....
I used to have a friend who was completely sold into this particular MLM. He went to seminars. He went to training. He enthusiastically tried to recruit me.
I was naturally skeptical, but out of fairness, I did go to one of the seminars. You know what that "seminar" consisted of? A highly affable recruiter who I admit was good at talking the talk. Also, we watched a video that resembled an early-morning infomercial, where the "president of the company" talked about how he made millions and you could too as he strolled through his Malibu-esque home, with his exotic cars parked conspicuously close to the swimming pool.
You should've been there. A crowd of at least 50 people, with a wide age range and ethnic background. However, they all shared one thing in common: They were all completely receptive to the sermon that they've been given. I was the only one complaining in the back, trying to talk my friend into leaving.
The moment I said anything contrary, one of the other recruiters asked us to step outside, closed the door behind her, and then did her heavy recruiting routine that consisted of, "You're going to miss out on a huge opportunity", and in a more subtle but obvious fashion, "You're an idiot." Eventually, I left, but my friend stayed.
Since then, he has bought dozens of items from their catalog to sell. Unfortunately, he was not able to sell his merchandise which, among other things, included special Eastern, ionized... virility water. No joke! So, he ended up using it all for himself.
He hasn't bought any more after that first batch because, by then, that particular "company" was declared to be an illegal scam in our fair city, and was subsequently banned from doing business here.
All told, my friend lost a few hundred dollars into the venture.
