It seems like people on the Internet have very short memories, or are just all somehow very young. The "past" goes back further than 2012. Bad times have happened before. Is this even worse than the late 80s/early 90s? We had much of the world still behind the Iron Curtain, the specter of nuclear holocaust, toxic waste dumps, acid rain, holes in the ozone layer, all things painted as much worse than climate change. I would rate the AIDS epidemic as quite a bit worse than Covid. There was a time not so long ago that it seemed a legitimate prospect that much of Africa just wasn't going to exist any more a few decades out.
If you go back to the 1930s and 1940s, now you're talking 25-50% unemployment globally, countries losing half their breeding age males to war, entire cities being wiped out in seconds due to nuclear explosions and not just the specter of them. Existentialism and post-modernism came out of that shit. We got Kafka and Sartre, things were so depressing.
Go back further and then what? Slavery? Post-industrial black lung? 8 year-olds working 100 hour weeks in factories?
When were things better than they are now other than some tiny blip of early 21st century techno-optimism?
As far as mental health is concerned, I guarantee you every male in my family that I ever knew going back to at least the 1920s suffered from severe undiagnosed depression. They all drank like crazy, beat the hell out of their kids, never smiled. The trauma they experienced was insane. My grandfather was ship-wrecked in the South Pacific by a kamikaze pilot and survived on driftwood for 6 weeks by drinking fish blood. I don't even want to imagine what those kinds of lives were like. Did it make it better that they didn't realize they were depressed and just thought that was what it meant to be a man?
