If a depression comes, people will soon have to choose between eating and paying their rent and utilities. Phones won’t even enter the picture.
I really think you're living in denial of modern reality. A smartphone gives you access to jobs among other things.
People spent in aggregate way more to accomplish fewer things before the iPhone (or equivalent high-end Android phone).
My smartphone is my primary camera, my communication device, my transportation lifeline, my business operations lifeline, etc etc.
I can't afford for this one thing to be the point of weakness. $1000 is extremely cheap relative to the value I get out of it - it would be a waste of time and money for me to skimp here. Not to mention, once you're in the ecosystem, breaking your workflow is extremely expensive so there's an element of lock-in.
Apple are in a stronger position than anyone gives them credit for.
The benefits have far outweighed any inconveniences for me in nearly 2 decades as a customer.
Doesn't mean there aren't issues, but in general I am very happy with the ecosystem.
Anyway this gets away from my original point. $1k is not a lot of money for what a smartphone is and the role it plays in our lives (which is only ever increasing).
It's silly to skimp on something so integral that you'll likely have for 3-5 years (or more!). All for what? Saving $500? This is why the high end smart phone market won't be impacted as sharply as you're predicting. People understand this.
