You need to worry when China starts exporting THEIR low-paying manufacturing jobs to US. It's going to happen sooner than you think -- their economic ministry already says China is not satisfied with only low-paying factory work (government as well as population, as noted above) they're going after the higher-paying tech jobs now. Corporate America is only too happy to oblige, what with their 3 month outlook on life. If your kids don't speak Mandarin, pick 'em up a Rosetta Stone in Shanghai while you still can. In 15 years, Chinese cargo pilots will be picking up bootleg English DVDs in San Francisco!
