You should take a look at the US from about 1880-1950... It's the case of every empire where things are built on the backs of the poor. Or in the case of earlier US, and many other societies, slaves.
That's simply how the world works. Sometimes it's a matter of greed, sometimes it isn't. The success of Walmart and Amazon seem to indicate that people will lean towards lower priced goods, period. Unless you don't buy any mass produced goods, and only source your needs to local crafts(|wo)men? Do you buy your clothes from a local tailor? How about your furniture from a domestic manufacturer?
Well, we better keep them in poverty while we work on making the world perfect. You can be the one to tell them that they world isn't perfect yet, so you're going to keep them in poverty until it's ready.
Who said the world is not broken? If it were not broken, why would we spend so much time trying to fix it?
People work in sweat shops because it is better than not working in a sweat shop. It is the bottom rung on a long ladder, albeit one that starts underwater in the sewer.
But it's obvious the world is already broken. It's not a stretch to infer by your post that you are implicitly passing some sort of judgement on the state of manufacturing jobs in these countries, and that is what folks are responding to.
