Answer:
Multi-level marketing.
Step-by-step explanation:
A business organization that is run with multi-level marketing strategy typically has 3 sources of income:
- The amount of money that each person have to pay in order to gain the membership status.
- The amount of money that memberships owners have to pay to be a distributor of their product
- The amount of money that they get from the sales of their product.
Most multi-level marketing companies will provide their members with some sort of 'Reward' if they managed to convert other people into purchasing memberships to organization. So, the more their members convert other people, the more wealthy that members will be. This will create a hierarchy like within an organization where the members who bring the most memberships place at the top of the hierarchy.
