MLMs are weird. Almost like the kind of thing they tell you you'll get scammed by in a third world country. It's one of those things where "Everyone knows..." it's a scam, but somehow they're still allowed to exist, nobody ever really warns you about it, etc, and people get sucked in. And strangely, some of the people are even fairly smart people. My friend's dad was a CEO of a small company and Columbia grad but still got sucked into the Primerica scam by the guy's motivational speeches and whatnot. I almost did, too, one guy just started talking to me at Walmart and me being somewhat outgoing actually don't hate talking to strangers, and told me about a job with a vague sounding title, and gave me a phone number and the address. I looked the address up in Google, and sure enough, Primerica. Didn't even go to the intro thing, just when he called said "Ah, I looked up the company and I don't believe it's something I wish to be involved in" or something to that effect, but the week emotional high from getting a potential job and having it turn out to be a scam made me sad.
Now I'm self employed as a contractor/handyman and it's hard as money is more sporadic, but you don't have to scam people.
