How so? I have a degree in electronics, have used macs for two decades and have worked on my own machines for years, I doubt the average factory line worker making Macs in China have degrees but I have been wrong before.
I think you missed the point
I have more experience in the electronics field than just about any tech you'll find in a service shop. I have experience working on the circuit level and repairing things on said circuit level rather than replacing the component part.
I'm one of the few people that you could bring something to, and have me replace the exact individual piece that failed rather than the whole controller card. I'll replace / repair chips, circuits, resistors, surface mount IC's / components, and repair traces. I've spent more time than I could count behind a soldering iron working on parts that required magnification to even see. I even had a business for a while (which I later sold) designing electronic devices and computer accessories (from my own circuit designs) and manufacturing and distributing them myself (including producing / etching my own circuit boards, cases, etc., and all the assembly work through to the end product). I later sold the company when I no longer had the time to keep up on the orders and manufacturing.
The point of my statement was not that they are more highly skilled. But, that they meet the one requirement that none of us could possibly meet.
Now, read carefully. The qualification they possess, is that they are...
... willing to work for less than 50 cents a day.
There you go. That's the single characteristic that makes them more qualified than any of us to build these expensive computers.
