Preach it, son. So much this. MLM's bother me because they seem to be manipulating market forces by their very nature.

Market: Hey, want to buy something? You get this much of a product/service for this amount of value.

Me: Cool deal. I'm in.

MLM: Hey, want to buy something? I'll give you a financial incentive outside of the actual value of the product/service so you'll work as my marketing engine to convince others to sign up also.

Me: So... you're telling me the product isn't good enough to stand on its own merit in the market place? Sounds like a real long-term winner there, sport. </sarcasm>
