I have my own thoughts on the lack of identity issue and I think a lot of it comes down to the internet making the World smaller in many ways. This may sound silly but I think of all the little towns around where I live, there are quite literally dozens within 15 miles, all of which when I was a kid, the people from different places all had slightly different things about them based on where they grew up. It’s hard to really extrapolate what these things were as they are all so individual and unique, it’s something you’d just feel somehow.
With the internet it seems to me that these people have kind of all blended into one of the same. The individuality has literally disappeared. You still feel it in the older folk, but the young guys from that town are exactly the same as the guys from this town. They all absorb the same content, they all live the same lives as each other. Perhaps generalizing, but the child of a farmer 30 years ago would be completely different to the child of a farmer today. The child of a farmer today is in very many ways no different from the child from the city.
The internet now raises people which leads to everyone kind of just meeting in the middle. No real identity, no real individuality, and most importantly, no real satisfaction in “I”.
