<human>: Can you condense the text into a few key points?

I don't know if this is the right subreddit, but I need some advice.

First off I know I won't join. My friends I've know M the guy and J the girl my whole lives since childhood. I got a text from J telling me about this great opportunity and I would be great for it. So I asked a couple questions and the question that confirmed it was a pyramid scheme was "did you have to pay them" and Js reply was " yes but only a one time payment and you'll make it back fast"

That's when I knew it was a pyramid scheme or multi level. So I need help on how I should talk them out of it. 

Secondly I have a meeting with MJ and their "leaders" tomorrow night. The only reason I'm going is so I can talk to MJ more and give them advice. But secondly is there anyway I can fuck with these leaders of theirs for taking my friends? Like when they are throwing their bullshit at me how can I throw it back?
<bot>: friends stuck in pyramid scheme, how do I convince them to leave? And how can I fuck with the higher ups?
