Not one person from the past 10+ years who approached me with a MLM pitch that I resisted and subsequently proceeded to mock me for my "Just Over Broke" (job) or working for "massa" is wealthy now, or even still doing their MLM.
I remember the first time I sat in on one of these obvious scams, it was Tahitian Noni, and they hyped up the product so much but the tell was instead of talking about how to actually sell this product they went right on to trying to recruit people for the downline (people who are lucky enough to get high up in MLMs get really defensive when you call it a pyramid scheme). I distinctly remember sitting through the sales pitch where they talked about the health benefits of the noni juice (helps relieve arthritis symptoms, resolves diabetes, lowers cancer risk, the moment where my inner voice started laughing is when he said "HIV" - this was the mid 2000s and the treatments they have for it now weren't common yet). They've since been sued and changed their name. Once you've had a couple friends approach you with this stuff you become attuned to it. "Hey man, I wanna talk to you about a business opportunity when I have some time" or an old high school friend hitting you up out of the blue then abruptly bringing this shit up.
