People, in general, practice deception all the time whether in traditional or nontraditional business. NM does not have a corner on deceit. The following week the store is closed. You call it. It happens all the time.

The idea of selling goods to people and encouraging them to sell the goods to others is merely Direct Selling on multiple levels. The distributor is selling the goods themselves. They are merely offering a value-added business opportunity to others who want to take advantage of it. The ultimate goal is to market more merchandise. It's managing, selecting, training, supervising, motivating and evaluating sales representatives.
