In 2011, in the US ~351,000 people were on the roles as individual sellers. The pdf even acknowledges "Single-level Distributors benefit from buying Herbalife products at a preferred price for their consumption and that of their families, and for many this is the only benefit they seek."
Those 351,000 people are the product for the "Supervisors"
Here's another one for 2013: https://opportunity.herbalife.com/Content/en-US/pdf/business...
400,000 people who earned nothing at all from herbalife as individual sellers (they could potentially profit from selling product, but that's quite rare, it looks like 50,000 people bought more than the minimum [see footnote in pdf]).
Next, 43,000 people who could potentially earn money from their downline (see the 400,000 chumps above); but only 2,300 actually did earn anything at all.
Next, the actual winners in the pyramid: 73,000 people at the top. But wait, 18 percent earned $0 and another 56% earned $250 on average. So how many people in the pyramid earn above minimum wage? Something like 2,600 people.
