it's not that simple, if it was that simple to build assembly plant operating corporations, everyone would do it, but it's hard business with very low margins.

There are a few big companies capable of providing apple with enough manpower/production capabilities. And even though it's a low skill work, workers still has to be trained, and more importantly have to have high work discipline(which could be considered a part of a skill set) Most countries don't have that at least in large enough numbers for companies like apple(and its contractors) to use.
