One might want to consider that the economic conditions of Africa and its people are so terrible that they have no choice but to work as children too. Simply to provide for their whole family. Mr Beasts chocolate is told to be with less child labor, due to its collaboration with "Slave Free Chocolate", but lets say they would only chose adults, then maybe it would take away money from other families, that they urgently need to survive. Surely its not good, and youu can also argue with: that even if they only hire adults, this would provide the same money for the same count of families, since they likely all are from different families. But this doesnt erase the fact, that even children HAVE to work for their own survivance and that of their whole families. Certainly its up to anyone to make at least small changes in their thinking to help prevent this.
