This document discusses multi-level marketing and examines both its advantages and criticisms. It notes that MLM firms sell goods through individual salespeople rather than traditional retail outlets. Some advantages listed are the opportunity to learn from more experienced marketers, low start-up fees, incentives for top performers, and the ability to work either full or part-time. However, it also acknowledges that many see MLM as primarily benefiting those at the top of the pyramid and question whether it is truly a sustainable business model.
