The title of this thread includes a question that cannot be accurately answered at the present time. But, I don't think you really wanted an answer as much as you wanted it implied that you're dissatisfied with Apple leadership.
High Prices and lack of features is the reason the iPhone is failing
This is nothing more than assumption without knowing all of the facts (manufacturing costs, infrastructure, R&D, royalties paid to other companies, overhead, etc). That, and the emoji you chose to use, make your agenda apparent.
I mean why $750 for a phone in 2018/2019 that has a 720p display ?
720 display? Which iPhone in Apple's current new device lineup, on the Apple website, currently have a 1280x720 px display?
And then the XS Max costing $1,500+ with taxes for the highest storage model.
I find it strange that you chose to quote the price of the highest storage model when the majority of people won't need a half-Terabyte of storage on a phone to begin with.. except that it is the best option to support your agenda.
I'm not defending Apple or their practices, I'm simply stating things as I see them. If you think you can do better, why don't you start your own company like Steve Jobs did? But, then again, it's easier to sit back and rant because that doesn't require anything from you today.
Change happens when the pain of doing nothing outweighs the pain of change. If you can bring better devices that work seamlessly with each other to the masses for a lower price, I'll will be among your first customers.
