The next time someone says they feel guilty for owning an iPhone, ask if they were the one who decided to maintain a 73% profit margin while underpaying workers on 18-hour-shifts. Did they decide to roll out new models at breakneck speed? To use conflict minerals and toxic chemicals? I didn’t think so. The most important ethical choice is not the decision to buy an iPhone, but the decision made on how to make, market and sell it.
