Over time you can make things elsewhere. There is nothing special about Chinese manufacturing that can't be done elsewhere. It may cost more to make said devices initially but can be scaled over time and cost less than before.

Manpower cannot be replaced. China has an almost inifite stream of people working like slaves and feeling 'good' about it. There simply are no such places worldwide at that scale.
