I suspect the main issue is that the kind of people that forge documents to get children into a job may also be the kind of people that wouldn't worry about fair work conditions or fair pay.
Beyond that, slavery/human trafficking is likely a part of the problem. Sadly, Apple moving elsewhere will unlikely improve the lives of those left behind. The underage workers will just have to get a different job, which probably isn't as good.
"When new violations are found, Apple requires its suppliers to return the workers back to a school chosen by the family and finance their education. "In addition, the children must continue to receive income matching what they received when they were employed. We also follow up regularly to ensure that the children remain in school and that the suppliers continue to uphold their financial commitment," wrote Apple in its latest report."
That's all fine for the handful of children involved here. The obvious plan is to deter further violations by firing the underage workers before they get caught, or not hiring them in the first place.
