"When everyone has signed up, who are you supposed to sell to? " About ten years ago IIRC, there was a pyramid called something like Women Empowering Women. It was centred on a small geographical area, the Isle of Wight. Anyway although a runaway success for the founders, so much so that it soon spread beyond its point of origin; it became blindingly obvious that everyone on the Isle of Wight was trying to sell to each other. Press attention ensued and the scheme went the way of all "guaranteed business ventures". Splat!
