In the part of the world I'm form, my childhood of the 90's to early 00's was exactly the same, and I experienced explosive increase in "stuff" surrounding me. Going from landline phones and phonebooths as status quo - to mobile internet just in 10 years. But I digress. Your point made me wonder - is it possible that the culture of material wealth - is the problem here? Could we have stepped on a poisonous flower - and now suffocating in the abundance of stuff we dreamed about as young people, now realizing, but not brave enough to admit that there is no meaning in it? And the optimism we had then, was a byproduct of a tighter communities, common struggles and just the architecture of life where we had to interact and care for one another more?
