None of these things would return if we brought back every factory job in the world onto American shores. If that were to happen, you would have to pay American workers the same wage as the factory workers in other nations. Otherwise, these companies would not be able to compete. For example, if Apple made every product in the U.S., they would have to pay their factory workers the same as Samsung or go out of business.
Is this a "Y4" character a low-grade mole or a startlingly ignorant moron? Does (s)he believe Apple, HP, and Dell are so inept that they have to have their products in low-pay countries while competitors like Samsung build in high-wage places?! They
all build their base model computers in the same countries, often in the same cities or even the same contract manufacturers' factories! If further configuring is needed, that is done at screwdriver plants in the US (specifically, Elk Grove, CA) or EuroLand. That's been the case for 20 or 30 years!
I suspect that moron has not walked the hallowed halls of Apple or HP. I have, as tech support for one of their vendors - a power supply company that sold its products to Apple, Dell, HP, Compaq, etc..
