This is a really hard problem in supply chains, it is not like buyers wouldn't change supplier if they knew about the abuses it is just that it is VERY expensive and time consuming to have proper traceability of everything in your supply chain. At the end of the day it is one very busy person putting purchase orders to some other very busy people. All of them on tight KPIs for their bonuses until eventually it gets to the production site and oops, child labor. To be honest this problem needs to be fixed top-down through international standards and institutions to ensure proper traceability. Leaving to each company to do it on their own and to country regulations is just stupid and counterproductive.
