Things have always been bleak.
I never understood the argument that everything is depressing for future generations when the entire human history has been dark.
WW1, WW2, Vietnam, Great Depression, Spanish FLu, Women couldn't vote until 1917, segregation, the cold war. I'm sure parents felt great when kids used to do nuclear war tests in the 1960s/70s
And that's just really in the past 100 years. What about life in the 1500s? 1600s? Before vaccines? Infant mortality rates? Women dying in childbirth?
It's not like humanity has been living in this rainbows and butterflies of nostalgia.
Life has always been hard, and will always be hard because each generations will face challenges that the other generations couldn't even imagine BUT there are challenges that our kids will never understand because it's different.
All you can do is raise your kids the best to your ability to be a positive contributing member to society, and try and make the world a better place. But that should be your goal no matter the state of society.
Edit: I would also like to add the addition of social media in today's generation has allowed these type of conversations to be had at this level. I wonder how society would view history differently if these type of discussions could be had regularly.
