They're paying the same. The root problems are still unaddressed, which is the import taxes on electronics. If the components they bring in are still taxed ridiculously, then there's only so much savings to be had by assembling them locally.
Assembly is a small portion of the cost of making a product.
And that's the case because of inexpensive labor in China, relative to here in the U.S. If the labor costs were 10x ($17.50/hr instead of $1.75/hr), assembly would no longer be a tiny portion of the total costs. Presumably, Brazil is somewhere between.
