I recall from another article that Apple requires 9,000 engineers to oversee the production of the iPhone. It is not that the USA has fewer than 9,000 engineers, but you would be lucky to find one engineer that is unemployed, let alone 9,000 of them. China, on the other hand, and perhaps Brazil, has engineers looking for work. Nothing is insurmountable with enough time and effort, but demonstrating that Brazil can easily accommodate a factory says nothing about the ability of doing the same in the USA.
