Probably because every generation says the world was way better when they grew up and from there point of view it has to be the end. I'm in my mid 30s and it's already starting to look that way, and I agree the world was a better place for every generation before us in most respects. The world was cleaner and people were nice, family meant alot more and peoples word actually meant something just like a hand shake. Technology has obviously gotten way better and made life way easier, but at what cost?
