I keep getting offered to join pyramid scheme "opportunities"?

[♥L_A_E]

More than once, I have been invited to pyramid scheme parties. They even go as far as to disguise them as social events. Recently, I have been asked if I would like to join in selling products. These are typically acquaintances, Any suggestions on how to politely decline with out offending their choice?

Tell them you don't participate in multi-level marketing programs, you're not interested. Say you respect that they chose it, but you don't choose it. If they push, tell them they're pushing, that you frankly think the whole thing is a scam, and that you'll listen after they and everyone under them has gotten rich, but until then. you're not wasting your time and money.
