A good network marketing company rewards leadership, just like any structured business.  Most businesses have a pyramid structure where the people at the top, ie. CEOs, SVPs, VPs, are the highest paid people in the company.  The unique opportunity you have with a Network Marketing   business is that you START at the top of your business, and your income will be dependent on how large of a team you build “below” you.
In April 2006, the FTC proposed a Business Opportunity Rule intended to require all sellers of business opportunities—including MLMs—to provide enough information to enable prospective buyers/participants to make an informed decision about acquiring/joining a business venture with information disclosed about the average likelihood of monetary profitability (and the extent of monetary profitability, if any) of acquiring/joining the business venture. In March 2008, however, the FTC removed "Network Marketing" (i.e. MLM) companies from the proposed Business Opportunity Rule, thus leaving MLM participants without the ability to make an informed choice of entering or not entering MLMs based on the disclosed likelihood of success and profitability:
Let’s face it, whether you call it multi-level marketing, direct sales, or network marketing, the entire industry gets a bad rap.  It’s often labeled as a pyramid scheme or get rich quick scam, and frankly, there is ample evidence to approach it with caution.  However, as I have studied trends in this business model, I have come to a very different conclusion.

Of those, the number working from home four to five days per week has jumped to 31 percent. Modern workers seem to be embracing the flexibility of working remotely, so it’s not surprising that multi-level marketing companies (MLMs) are “poised for explosive growth,” Forbes predicts.
Then figure out where your target customers can be found—both physically and virtually. College students who need more income can be found on campus or on online forums or websites about learning to manage your money. Athletes and people who lead healthy lifestyles can be found at gyms and online groups or websites about running, yoga, healthy eating, and more.
MLMs have been made illegal in some jurisdictions as a mere variation of the traditional pyramid scheme, including in mainland China.[10][11] In jurisdictions where MLMs have not been made illegal, many illegal pyramid schemes attempt to present themselves as MLM businesses.[7] 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.[4][19][20]
