As soon as the USA fixes the tax system to make it better here and also the regulations involved for setting up those factories, then fine ... I’m sure Apple and ALL THOSE OTHER COMPANIES who do that will come back here.
BUT ... as it stands right now, Apple is ALREADY employing a HUMONGOUS number of people here in the USA and is manufacturing here, too, for some of their products! It’s ALREADY HAPPENING with Apple!
What percentage of Apple's workforce, direct and contracted, are US citizens?
"HUMONGOUS" is what's known as a "glittering generality", and not worth spit.
