I agree with the OP. I am originally from a 3rd world country (one of the poorest in the world) but had the fortune that my father managed to emigrate to a western country. It's no good reading about it in a book or newspaper, that stuff from Slumdog Millionaire does actually happen.
When your next worry is where your next meal is going to come from you really don't care about child labor laws, education or better health. If you can't afford food, it's unlikely you can afford the other two. It seriously is a case of bringing in food for the whole family for some of these people.
Edit: This may be too idealistic because Samsung and others seem to get a free pass, but no American company is going to get away with child labor regardless of how bad other countries companies are behaving, I have no problem with that fact. Let lesser countries take the low road.
