I mean we just limped through a pandemic, have rising inflation (no wages haven't keep up for decades), could see a recession/depression soon, kinda need to be worried about fascism again, and have climate change to deal with. I probably forgot about some stuff too.
The past is often tented in our minds either due to limited information of that time or because we were a kid at the time. It is also true that a lot of stuff is better. Still, people have good reason to worry about the current state of the world.
