They report good conditions on what they are allowed to see and what they are told. I've seen some of the videos of those adolescents working away. Most of the videos are shot very cleverly to avoid you being able to tell they are young children. I'm not going to defend companies/countries who make children work.
You know they are adolescents how? We have a large Chinese community here and I known that 18 year olds can look younger. So you don't have any 18 year olds and younger working in factories in the US? We have teenagers who leave school and take factory jobs here.
