Excellent Penn & Teller program on multi-level marketing . BTW, NSFW. Those who are easily offended, shouldn't watch it. Any of it. Not one minute..... As Penn & Teller rightly point out.... Easy Money Is BS These multi-level marketing schemes aren't limited to home parties for sex toys, BBQ accessories, and household cleaners, of course. They are rife on the internet. If you've spent any time in internet marketing circles, you'll have seen hundreds, no doubt.
