Actually it does. Workers on Apple's assembly line are using high-tech tools and need to be able to work controls and be able to understand what they are doing. Many of them are testing things as they do them. They have to read dials, verniers, measure, etc. It is not grunt work. . . of course some is actually grunt work, but some is fine motor skill work.
Give me a break it takes 5 minutes to learn those jobs....
