Do you think that is good thing or a bad thing? Your post told me you don't think this is good for the USA.
“who has been to China and ALL of their factories to verify that cheap and child labor are not still in use to manufacture stuff for Apple []?”
Focusing on Apple as the subject of this thread...
Tim Cook, IIRC.
Knowing they’re a primary target for trolls like yourself, Apple goes to great lengths to not just ensure minimum standards are met, but that they are well exceeded so there is no room for arguing/blaming. As others noted above, there are severe consequences for contractors that violate such laws & principles - we’re talking BILLIONS of dollars in lost revenue for petty screwups. All know full well that “turning a blind eye” can cost _Apple_ $billions, so they ensure such doesn’t happen.
Remember: wages for building Apple products are about 3x regional norms, the much-lambasted suicide rates are substantially less than the regional average, child/forced labor rates are basically nonexistent under Apple’s umbrella (have you any proof that there ARE such violations? rather than insisting proof that no such thing happens anywhere?), etc.
Not sure why you’re so he11-bent on slamming Apple. They’re doing very well precisely because they’re trying really hard to do very good.
