Because pyramid sales plans are by their very nature deceptive, they have been made illegal by the Minnesota legislature. There is a real risk that a pyramid operation will be closed down by police and the participants subject to fines and possible arrest. Pyramids are deceptive. Participants in a pyramid, whether they mean to or not, are deceiving those they recruit. Few would pay to join if the odds stacked against them were fully explained.
Pyramids are losers.
Pyramids inevitably collapse because it is mathematically impossible to recruit the numbers of people required to support the pyramid. Pyramid promoters are masters of group psychology. At recruiting meetings they create a frenzied, enthusiastic atmosphere where group pressure and promises of easy money play upon people's greed and fear of missing a good deal. It is difficult to resist this kind of appeal unless you recognize that the scheme is rigged against you. The sale of legitimate products is what distinguishes multi-level marketing operations from pyramids.
