Apple doesn't employ 100,000 people to make the Ipad and the Iphone, that work is done for them by Foxcon (Taiwanese company that does its work in China), they employ a lot of people, but it isn't just the iphone and ipad, they build for a lot of people, they are a contract manufacturer, the way Sanda Kan was with trains.
I believe in 2021 thats a given. I didn't think that needed clarification.
"The factory, run by the Taiwanese electronics manufacturer Foxconn, employs about 350,000 people and produces about half of the worlds I Phones. In the busy summer months before the fall release of a new iPhone, the factory produces 500,000 phone a day or up to 350 a minute."
They "might" make more phones in one day than than Lionel has made locomotives in 100 years.
