This is the legacy of Tim Cook before Jobs passed. He was the guy who put immense pressure on Chinese factories to deliver on the insane quotas and timeframes he forced on them. He essentially blackmailed companies in order for them to his bidding - threatening to go to competitors if they didn't deliver exactly what he wanted.

The stuff Apple got away with in China could never be repeated here. I mean, you think you can regularly push so many workers to commit suicide, you have to put nets around the buildings in order to dissuade them from jumping off buildings? Yeah, not happening here. Which is why Apple does business there. Its why Tim Cook was able to abuse Chinese labor laws to get them to deliver the impossible, time and again, regardless of the human cost.
