I think the point being made is that if Apple/whoever was willing to pay for it, you can setup the supply chain and get the workers wherever you want. It might cost more, sure, but it can be done.

However, you can't just extract energy from somewhere that doesn't have it. No matter how much money you want to sink into it. If there's no oil/NG/whatever, that's that. Trillions of dollars wont make it appear there. Trillions of dollars does let you setup a nice supply chain and labor force in the US though.
