I think it's silly that Apple always ends up being the target of this sort of complaint. Are any of our electronic devices manufactured in quality, safe facilities where workers are given 40 hour (or less) work weeks, vacaction time, full medical benefits, and a 401(k) plan? Is your Droid or Windows phone manufactured any differently? How about your TV, PS3, or Blu Ray player?
This is a commentary on 2 things:
1) Working conditions in China
For this, the Chinese government will need to be persuaded to change their policies to protect their workers more. Either the people of China rise up and demand better working conditions, or people around the world stop buying their stuff. Without that change, the horrible working conditions there are essentially legal and will continue.
2) A company's desire to produce their electronics cheaply and very quickly.
Cell phone makers can't produce their hardware in the US. It'd be a beautiful gesture if they could, but it's impossible. The cost to do so would mean that your $200 cell phone would suddenly cost $500 and your $500 cell phone would go for maybe $1000? Beyond that, the US, and many Western countries lack the necessary infrastructure to manufacture technology at the speed and volume that occurs in China. Will the US make the dramatic changes necessary to "bring jobs home", as everyone always asks for? Would US workers be willing to make $5/hour to support this new industry and guarantee a shift in global industry?
I for one don't like the fact that everything I buy comes from somewhere in southeast Asia, but our society has been embracing this change for decades, and to change it from what it is now will require immense effort by many people for many years in order to know that all of these great toys we buy aren't the product of underpaid, overworked, tortured people.
