When I take a flight, I don't demand to know how much the airline is paying the pilots and flight attendants. When I buy food from a restaurant, I don't demand to know how much the restaurant is paying the waiters and cashiers. I also don't know how much the restaurant paid for the food they cooked. That's true of any company/workers/suppliers. People only know and care about how much they end up paying. As long as there's a minimum wage, people don't know, and usually don't care how much a company pays their workers/suppliers.
