I just don't think Apple has any pressure (at least, not in the next couple of years) to give into the herd mentality and make cheaper devices. That's especially true when Apple is doing very well in China -- you know, the place where everyone says you "must" compromise on profit and quality to succeed. In North America, the higher price of flagship phones still isn't as much of an issue because payment plans typically mask the cost. You might pay $25 per month for that new phone, but you're also getting a discount on your monthly bill.
And it's hard to say that the iPhone will necessarily mirror the Mac. The pricing is considerably lower (and thus more favorable), the customers are different (just about everyone can use a phone, not everyone needs a computer), and the competition is different (in China, for example, there's room for both mass market and upscale brands). With that said, I don't think Apple is going to change its mind either way. It's both stubborn and aware that it's wiser to play the long game. Too many companies scramble for market share at all costs and don't realize that very few vendors ever 'win' that war, let alone enjoy the rewards for more than a short time.
Just ask Samsung: its goal has (as far as I can tell) always been to win by having the most sales. That's why it spends amounts on marketing that would make Apple blush, develops phones for seemingly every niche and gladly compromises on build quality and performance if it means lower prices and reaching wider audiences. That only worked so long as there was no other major vendor that could undercut Samsung... and, well, Chinese vendors can undercut Samsung. It was only in mid-to-late 2014 that the company seemed to acknowledge that its strategy was no longer all that effective.
