There's a good arc in NPR's Planet Money that touches on this angle. Not necessarily the need for this labor, but how the work travels around developing nations and what it means.

I forget the title, but the series is essentially how they design a T-Shirt for the show, then follow how it's made; from the cotton harvesting up to the final shipping container hitting the US. It should be easy to locate.
