Multilevel marketing (MLM) companies, such as Herbalife and Mary Kay, generate nearly $30 billion in U.S. sales by utilizing independent salespeople who earn through personal sales and recruitment. Critics argue that MLMs resemble pyramid schemes, although the Federal Trade Commission distinguishes them based on whether income is generated primarily from product sales. Despite some top sellers earning substantial incomes, the majority of salespeople earn modestly or sustain losses after accounting for upfront costs.
