Technically, the Epstein class still sends children into the mines. Not in person of course. They had a chain of command back then, and they have it now. Back then, it was all their own management inside their country. Now it's multiple companies between them and the children in the mines. Sadly, these rights have to be fought for in every single country anew. Hard to do while the country is trapped in eternal war though. Congo never had a chance.
