We need to keep things in perspective. To most of us, the idea of "sweatshops" sound horrid, and they may well be. Especially when you think about safety standards and such. On the flip side, look at it from the workers' point of view.
One of the books I read recently talked a bit about this, and this opinion article expands on it.

These workers are not slaves in sense that they are being forced in to it. For as bad as their conditions are relative to most of us, these are many times the better options for these workers. They willingly choose to work those factories, and many times are paid well compared to their other options. If those factories closed (as can very well happen if firms pull out to save face or stricter standards/wages are pushed on them), those workers are likely to face even worse alternatives.
I'm not saying any of you should choose to deal with a manufacturer or not based on their foreign practices, just playing a little devil's advocate because the issue is always presented so one sided. If factories continue to pull out, then the workers will suffer more. If conditions are arbitrarily forced to improved through increased regulations, then the workers will still likely suffer through reduced wages. The third option is we pay a lot higher prices for these products to cover the added costs of increased working conditions and wages.
And if we go with that third option, that still may not work out well. For example, the U.S. has a long history of being a premier manufacturer before so much was offshored to avoid growing regulatory costs and to find cheaper labor. If we have to pay almost the same price for something from China as we do for something made in the USA, most people here are likely to opt for the U.S. made product. Manufacturing would start to leave those countries to move here, thus still leaving those workers in worse conditions than they are now.
