Recently I heard that every person in a wealthy country effectively makes use of two slaves this way.
So these products being hard to track is no excuse. We should not allow the import of products where there's any uncertainty about their supply chain. Tech giants should have a responsibility to know where their minerals come from.
And this is not just about electronics or about the DRC. I think we shouldn't let our football teams play in Qatar stadiums built by slaves. We shouldn't be importing clothes made by child labour. We shouldn't be importing from countries that don't respect the rights of workers.
We're undermining our own freedom as well as our own economies by allowing this. We're indirectly abusing people in other countries, but we're also expecting out workers to compete with them. It's undermining everything we fought for over the past century.
