You are completely correct about society needing more, more more and failing to understand that consumerism doesn't buy happiness. In fact, the constant drive at new or the latest things can more often than not bring disappointment and depression.
Imagine a person buying the latest phone release and feeling awesome...only to realise that the next new one has a better camera...Their first one, that they were content and happy with, now brings them anxiety; it's not the latest thing. So their brain justifies the new purchase and credit steps in. They feel good again...but only until the next best thing comes along. It's a slippery slope. People attach the feeling of self worth or esteem to the things they have but it often has the reverse effect.
I know just that type of person. One of my work colleagues literally sleeps outside the London Apple store when any new phone is coming to ensure that they have the newest phone possible on the day its launched. Their "feel good" therefore comes only with their feeling they have the latest not because of really enjoying and getting the value from utilising what they have.
I just don't get the mentality that drives people that way. My phone is 3.5 years old. It wasn't cheap but I use it heavily, and not by that, I mean I use it for a lot of different features it has. It is still a great phone and serves the purpose I have for it very well despite not being the newest. It was a good buy. I have more than consumed the value of the original purchase.
A total twat.
I have nothing against quality purchases, in fact, I put quality over quantity...But I certainly don't feel validated in any way through the purchases I make. I'm all about experiences, generally in life, rather than things. I bet that wanker that lines up at the Apple store won't be laying on his death bed saying things like, thank the almighty I bought that iPhone 13. (Or maybe he will.)
