I remember all the fuss back in the 70s. "Hey, grab your whole family and friends and check out this money making enterprise, it's great". I went to two of these meetings just to appease friends and some family member. It was advertised for exactly what it was, a pyramid scheme. Some smiling dudes with a large chalkboard with a pyramid drawn on it with squares. No products or services provided except for talking folks into handing over money and for them to find others to hand over their money. It was clear to me as a kid, not many can fit at the top of the pyramid.
