No. These kids were schooled but pressed into working at the factory, they didn't drop out. They don't do it for the money, and it is possible that neither them nor their families receive any compensation. The alternative would have been doing homework at home or playing, not the kinds of "jobs" that you've mentioned, at least not in this particular case.

Such a practice is/was actually quite common in (ex)communist countries specially for seasonal work when regular workers weren't enough, like during the cotton harvest in Uzbekistan, and was also organized by the teachers. Shocking for us but culturally acceptable out there.

This is just a modern version, a stopgap for labour shortage, that happened to make it to the papers only because a western company was involved.
