Whether or not confectionary companies import chocolate with slavery working is not responsibility of consumers. It's on companies who hire children illeagally ,and those who beg extreme discount on exporters in developing countries. Consumers don't have to be worried about how much money workers were earned to produce goods.
Managers of the companies earning illeaglly must be responsible for slavery.
