None of these alternate assemble sites are located in particularly stable democracies. It wasn’t that long ago that Thailand suffered a military coup.
Manufacturing in USA is hardly profitable for Apple (Unions alone would force Apple to double its costs).
As an alternative I was hoping they would relocate to Central American republics... Guatemala, Honduras, Bitcoin-loving El Salvador, even Costa Rica, which is welcoming of American tourists.
I'd imagine it would be reciprocal... Apple factories would provide thousands of skilled jobs for those impoverished Central American nations, and hugely raise their standards of living. Also, Apple factories in Costa Rica is a very low geopolitical risk, since Costa Rica cannot militarily threaten the USA or Apple.... whereas China is a nuclear threat to the USA, and China has the easy ability to sink US Aircraft Carriers in the Pacific, and China can easily seize (nationalize) Apple factories in the event of a Pacific confrontation.
Lastly: if Apple provided thousands of skilled stable jobs to Central American republics, that means thousands upon thousands of families that will actually have less impetus to immigrate to the US illegally.
It's a win-win-win situation for the USA, Apple, and Central America, if you think about it.
