As my uncouth grandfather used to say: “Wishes in one hand, shit in the other, which will fill first?” These children work because they have no choice. They are paid these wages because they can’t make more.
I suggest empowering women who don’t want children to not have them. If we look at the developed world, it is clear the total fertility rate will settle far below replacement rate (2.1) and child labor will dry up when women are educated and have robust access to family planning.
Perpetual labor shortages are a better outcome than surplus labor and lives of suffering, most especially children suffering.
By all means, open your wallet to pay these kids a living wage. I’ll even help you bootstrap the direct cash transfer mechanisms via mobile payments if you have deep pockets. But that is unlikely to happen. Hope is not a strategy.

According to the publicly available data discussed in more detail below, Sub-Saharan Africa is the region where child labour is most prevalent.")
