So, what happened next, in short, is that the Chinese factory was contacted and—in order to keep to schedule, which Apple refused to change—the foremen woke up all the line workers, who were asleep in their company provided dormitories, roused them out of bed, told them that there was time enough to get dressed and have a quick cup of tea, after which they would have to get their selves onto the assembly line and start work immediately, as there had been a big change.
This is not going to happen in the United States—ever. And this, above all else, is a big reason why companies want to use Chinese manufacturing.
I share this only to raise the point that we live in interesting times, and they're about to get even more interesting.
