Don't know what you're going on about. Yet again someone using the word "overpriced" without knowing what it means. If iPhones were overpriced then they wouldn't be selling 200-300 million per year. They might be classed as expensive by some, but then again so are many of the other latest flagship phones, some even more than the iPhone 6S. As for not being able to afford an iPhone, there are various ways to get one, there are five current models (iPhone SE, iPhone 6 & 6 Plus, iPhone 6S & 6S Plus) for a start all at differing price points. You don't have to buy your device outright, there are contracts at differing prices along with the newer instalment plans. A chance for anyone, regardless of income to get a foothold on the iPhone ladder. Then there's the refurbished/used route which a lot of people take, you can easily pick up a now discontinued iPhone 5S at a great price as retailers sell remaining stock.
Apple wouldn't go for the price it lower and go for volume business, they'll leave that to Android manufacturers. And just as a correction, the offshore workforce is not Apple's it's Foxconn/Pegatron, etc. and these Chinese companies manufacture goods for several large tech companies not just Apple. It needs the entire industry to raise wages, Apple is very vocal about supplier responsibility and gets a hard time over it while others remain silent on the issue.
