Should Americans Care About Apple’s iPhone Factory Conditions?

Inasmuch as the thought of it, and the guilt you feel for supporting it, affects your decision to buy, yes. Otherwise, no.

The USA is NOT responsible for the working conditions in any other country, even though Apple clearly condones it. If Americans really cared, they'd eschew Apple for other brands, but they'd probably find pretty quickly that those other brands have similar work situations in their suppliers camps.

Additionally, even though China is not as freely capitalistic as we are, those workers still have the God given right to not engage in that work, or to seek work elsewhere.

Based on what I've heard from friends in China, the workers know going in that they will be pretty much held hostage working for just enough to pay for food and housing provided by the companies they work for.

Choosing to do so is still a choice, and if they have choice, they can still say no.
