If having an iPhone is a symbol of “affluence”, half of the US is affluent.
Your anecdotal evidence doesn’t jibe with broader statistics.
Edit: For complete transparency, I am seeing ranges from 42% - 50% market share in the US depending on the site.

I mean, it's probably the richer half that owns iPhones, so it's consistent with what you said.
I guarantee you that if most of your friends have iPhones, your friends' incomes are probably on the higher end, statistically.
Don't those payment plans require good credit, anyway? A lot of my friends don't have that.
But, after you have been a customer for awhile for a carrier, they take your on time bill payments with them into account - at least with T-mobile.

I live in the SFBA, hang out with people at all income levels, and I'd say over 70% use Android. Among richer people it's more 50-50.
It's pretty easy to get USB-C chargers among my friends.
