Things to break down here...

When manufacturing products like this, nobody is using a soldering iron, and certainly not in volume. Its all pick and place + reflow + wave soldering (river of solder).

However, when absolutely needed, say phone/laptop repair, you absolutely are "skilled" labor if you can work on these devices.

What do we have to do to be skilled to you? Build a ship in a bottle while juggling flaming bowling pins?

What makes it skilled is the amount of soldering points you have to make in an hour, and the grit you need to maintain that rate because you have no choice. The same kind of skills that orange pickers in the US south require, and is more abundant in Mexico apparently, than in the US.
