Yeah you bring up a good point. I can't imagine assembling iPods is the most engaging activity ever, and most Americans would probably scoff at the kind of labor they seem to think is below them.
Kind of similar to when they raise an uproar about illegal immigrants taking all the jobs away, when they wouldn't be caught dead doing the kind of work some immigrants do.
At 10% unemployment, I don't know many people who would scoff at a job these days.
And, it isn't that illegal immigrants do jobs that people "wouldn't be caught dead doing" -- it's that they do jobs that people wouldn't be caught dead doing for below minimum wage. There are plenty of Americans who would pick fruit or clean buildings for a fair wage -- they just don't get the opportunity because an immigrant will do the job for cash at poverty wages.
