> It could be as simple as just forcing companies to source responsibly and only work with suppliers that have some really strict policies against using child labor.

We can't even do that with coffee, water or palm oil (just to cite these). Cloth/shoes companies are still using child/slaves, most tech product still contain materials mined in very shady mines by kids/slaves in Africa.

"it's simple", "it's just a matter of", "we'll fix it in the future", "it's just an opportunity to find solutions", this is all wishful thinking.
