Also consider companies that may impact you indirectly. Many businesses don't ever deal directly with consumers. When you go to check out at the supermarket, who makes those machines that take your payment? When you buy your medicine at the pharmacy, who's actually making those drugs? What equipment are they using? When you get your car fixed by a mechanic, where do they buy new parts and who makes those spare parts? When the signal on your phone drops because there's not a cell tower in sight, who's really responsible for building new towers and who makes the equipment that goes on those towers?
