I know it.
But MLM is just a form to distribute to a commercial structure (pyramid, ok that's clear) the rewards for a profitable positive word of mouth.

Even the pension scheme is a pyramid then 😅: the youngest to word and the eldest to get the money.

I think that MLM is just a way for companies to bring products to the market and instead of medias, press, tv announcements, advertising spots, they use people satisfaction to breach into the market.

But yes, I am an engineer. geometry is not an opinion and MLM is a pyramid. I just say that may be a clever pyramid for people that manage to be clever in doing such activity.

But I can stop here. It's the last day of the year and it's time to go get some food and drinks for a proper party! 😎

Best wishes!!
