First, hopefully you can agree that, fundamentally, the company paying these child workers is trading money for labor. (This shouldn’t be controversial, it’s a fact of labor markets.)
Second, the companies paying these children are extracting value from their labor greater than what they are paying the child laborers.
Third, the employers chose laborers located “predominantly … in East Africa, Venezuela, Pakistan, India, and the Philippines” for this work because that’s where they can pay the least in labor costs while still extracting value.
Fourth, keeping labor costs as low as possible while extracting maximum value is the most rational course of action.
Fifth, and finally, it is very rational for children to seek out & undertake this work — to exchange their labor for money — given the economics of their lives.
With these predicates laid out, my point: The reason your analysis doesn’t lead you to thinking this is a raw deal for the children involved is because in a sense, it’s not. Given the economics of their lives, this is, relatively speaking, a good deal.
The rawness of the deal only becomes apparent when we start to inspect why material conditions are such that this deal — trading an hour of labor for $2 to a company serving a multi-billion-dollar market — is enticing to children.
In other words, this article, in my analysis, is an opportunity to study and question the system that creates the conditions such that there is a labor market comprising children who are available for exploitation for cheap labor by very rich Western companies.
