Apple this and that...
I've no love for the folk at Cupertino, but to single them out is a little disingenuous - as in this article http://www.businessinsider.com/apple-child-labor-2012-1 - you have to read till the bottom of the article to find this small, parenthetic comment:-
(Not that Apple is the only company choosing to avoid American labor rules and costs, of course — almost all manufacturing companies that want to survive, let alone thrive, have to reduce production costs and standards by making their products elsewhere.)
Indeed, it is to the credit of Apple that they are publishing this list, perhaps it is a sign that they will be a little more careful in future as to their partners.
For years our jeans and trainers and all the other goodies we take for granted have been made in countries where dubious working conditions are the norm - we've known about this for decades, but little is done. Hopefully, as the GDP of these countries increases, workers rights will increase as did workers rights in the UK during the industrial revolution - where conditions were as bad as the ones mentioned.
Cutting off your nose to spite your face and boycotting these products is probably futile at an individual level, but lobbying your representatives may help - exposure by responsible journalism, probably more so.
