I don't think the "realistic" vision I had of "the world" has really changed, just the attitude: I'm still "stupid as f*ck" and observing "person X I knew in high school totally has such a better life than I do" - but now, it's about interpreting it as a reason that things should probably change, whether it's the perspective ("So what?") or the action ("Are you not even going to try doing something about it?").
OTOH, it really doesn't help that there are so many more things to be depressed about pretty much all the time - abuses of social media, pornography, addiction, fracturing social structures. I ask, incredulously, how can anyone read this [1] and NOT want to die, or at least profoundly sympathize? People haven't evolved "rosy enough glasses" to mask these symptoms of modernity - of course there are problems, both with "the world" and our abilities to get by.
"How shall we comfort ourselves, the murderers of all murderers? What was holiest and mightiest of all that the world has yet owned has bled to death under our knives: who will wipe this blood off us? What water is there for us to clean ourselves? What festivals of atonement, what sacred games shall we have to invent? Is not the greatness of this deed too great for us?"
