FoxConn has (apparently) about 920,000 employees. Assuming 1/3rd of them work only making Apple products then triple that number based upon the ancillary jobs supporting those employees (any sub manufacturing) like how Apple's website calculates I think it would end up being 920,000 people have jobs in China because of Apple.
