The classic development-studies conundrum - halting exploitation in many cases is a worse outcome due to some employment being better than nothing for many people.
The cocoa trade in Ghana is an example - kids work 3-4 hours per day on family cocoa farms, yet this income enables the families to send their kids to school (where they often still complete 1-2 hours of agricultural work per day as many schools provide a basic meal as well). Child labour is often welcomed by the children themselves who feel a sense of pride in contributing to the family business, yet makes tracking illegal child labour much more difficult and leads to selling/exploitation of children is some circumstances (far more prevalent in the Ivory Coast).
Similar situation with Foxcon workers in China.
People need to remember we in the West went through the exact same thing. People might ask "well why can't they learn from our mistakes have fair progression." I would argue they are. Their economic transition is far more organized and stable then ours was.
