Mostly on the radio I hear about Apple and Chinese labor, so they seem like a multinational company more than an American company even though they do "command and control" from the US.
Also they don't employ a huge number of Americans compared to other large companies (and excluding retail they remain pretty small, esp. compared to Microsoft). Maybe the valley is different too, because a large proportion of the population are immigrants.
More data: they employ many Americans, and the campus is filled with them (of all sorts of ancestries, not exclusively imigrants from India or China). According to http://www.wolframalpha.com/input/?i=aapl they employ a number of people adequate to sustain a revenue/employee of $2.351 million/year. The factories are not Apple's, but are contracted manufacturers, the same used by many others (Dell, etc).
I agree with you about linking Apple and Chinese. When I think of the Apple labor force I automatically think Foxconn, which leads to thoughts of labour camps and worker suicide, not that that's the whole picture of course.
