Given the history of child labour laws in england, i can't help but being skeptical.
But i don't know how accurate my information is. 1) children used to work in coal mines in the UK; 2) children who worked in coal mines didn't grow up to he healthy strong adults; 3) Coal mine owners needed strong healthy men.
Thus it was in their interest to ban all child labour ( to prevent children working in any of their competitors coal mines, so they had a greater supply of strong men )
Ok, that may have been true back in the 19th century, you say, we have democracy now you say...
But this may be seen as a type of trade war / protectionism (under the banner of child rights) that the impact of reducing purchasing from foreign companies will benefit local business more (though i don't think local cotton production in England exists any more)
I can't see fair trade being used in this way; but banning products like this does seem like a good cover for economic warfare.
Meanwhile, in Ireland at least, there are women who are not allowed work (due to thei refugee status still being processed, for 7 years) who prostitute themselves to help pay for their children's education and/or food.
The government tries to make them stop working (prostitution is illegal) which effectively cuts of their only source of income. Cutting off anyone's only source of income is a bad things, even if you don't approve of how they make it.
Of course these women have some voice, so i can listen to what they say on the matter; the children in some undisclosed foreign country are not people i can talk to, and may be scared of losing their jobs if they speak out... So i can't tell you what is best for them.
PS: can anyone research the original band on child labour in the UK? Are the transcripts from the arguments made at the time??
