>Perhaps it's social media that makes that they are either too aware of it or simply mention it more often.

Here's a question for me to understand where you're coming from and you to examine your assumptions. How does "too aware" get defined? Who defines it? I am an 80s kid(though grew up in India) and seen some issues myself, but can't claim I am worse off for knowing what I did. And to be clear, I didn't have internet till the start of the millenium and relied on books, radio and newspapers and I still was more about the state of the world i was to inherit than my parents.
