As the owner, you are the face and voice of the product whether you like it or not. Expect to spend an inordinate of your time managing people, their emotions and expectations. The heavy reliance on residual income means that your income stream may dry up suddenly if a salesperson fails to meet his quota. This could easily happen, because in many cases that salesperson must not only be accountable for his sales, but of the sale people he recruits under him. These are people he may not know. Therefore, your earnings potential is limited by the selling ability of others not directly under your control. A MLM business may strain your personal relationships. Lower-tiered salespeople, particularly those within your circle of family and friends, may harbor ill feelings if they fail to advance within the organization.
MLMs have been made illegal in some jurisdictions as a mere variation of the traditional pyramid scheme, including in mainland China. In jurisdictions where MLMs have not been made illegal, many illegal pyramid schemes attempt to present themselves as MLM businesses. Given that the overwhelming majority of MLM participants cannot realistically make a net profit, let alone a significant net profit, but instead overwhelmingly operate at net losses, some sources have defined all MLMs as a type of pyramid scheme, even if they have not been made illegal like traditional pyramid schemes through legislative statutes.
