THe probnlem is assembling the damn things. it is very precise work requiring specialized knowledge.
Yes, and no. It is precise work of the sort that is no longer taught in all primary schools. On the other hand, it more the sort of thing that requires some training and some practice, rather than "specialized knowledge" or rare skill. If you meet a random person on the street, could they do the final soldering of TH components on one of today's electronics products? No, probably not. But you could probably train them to do so in a matter of days or weeks, and after six months you'd have a subset of people who were really good at it.
I keep thinking of the "ladies" who used to assemble Core memory. And assorted physical laborers (gardeners, construction folk, etc.) Do they have Skills? Hell yes. Do they have unique skills derived from years of study that would be impossible to replace? I don't think so...
I suppose that it says something about society: the amount of time that a company is willing to spend training an employee to do what it wants. It seems to be at a low point at the moment; perhaps a symptom of depressed economies where the chances of finding someone out-of-work who already has the skills you want is higher. (OTOH, you had/have professions that are artificially restricted by demanding that would-be employees do lengthy apprenticeships, even when it's probably not strictly necessary. That's not so great either. IMO.)
