This! Also, why does it matter? Unless any of you are married to another or live in the same household, it’s none of your business how, or how much, anyone paid for their phone.
Because this type of thinking is squeezing the middle class out of existence. 2 year (soon to be 3 year) phone loans, 84-month car loans, interest-only home loans (they are coming back, yay!) are all tools used to allow companies to increase prices to a point beyond what most people can realistically pay. It masks your inability to pay. At some point we all need to not have to have the newest phone every year. Honestly, if you have a X, how can you really justify the purchase of a XS or XR as anything other than I want the new one?
You are correct. It is an individual's decision. However, as much as we wish it were true, that does not happen in a vacuum, and currently there are enough individuals making these decisions for Apple (and a whole host of other companies) to continue raising prices to new heights and squeezing the life out of the middle class (and just destroying low income) because they tricked us all into having to have the newest one every year. Sooner or later the debt will crush the economy again, and the outcome may be potentially worse next time.
