There are 100's of thousands in this world who would risk their lives to work in this factory for half as much.
Unless the people were forced to work at gunpoint, this is the sad truth.
The working conditions may seem cruel to us, but "good wages" are relative. This is the first (often ugly) step in economic development.
This kind of labor is far more effective in aiding populations than direct financial aid, which is almost always squandered.
