"Some of these businesses are small diners or independent grocery stores; others are franchisees that own a handful of stores affiliated with a recognizable brand. (For instance, over 80% of McDonald’s locations are owned by franchisees.) In either case, the profits and executive pay at the country’s largest businesses have nothing to do with the stark economics these small-business owners face: single-digit profit margins."

If over 80% of McDonald's locations are owned by franchisees, then it's likely that MANY of these are franchise-related (also, profits and executive pay at McDonald's would certainly have something to do with the related economics of franchise fees and the back-end of the supply chain).
