In my experience the young tend to exaggerate highs and lows because they tend to have lived through one and not the other. This is particularly true because many people today have no memory of actual recession. Far fewer have any memory of war (in the West in general and the US in particular).
The last few years have really exposed just how profoundly irrational and profoundly selfish a significant percentage of the population is.
So take climate change. Yes, it's a big issue but my view is now fatalistic. Humanity won't even minorly inconvenience itself to do anything about it. So we'd better hope there is an economic solution, specifically an eenrgy source without greenhouse gas emissions that's cheaper, because nothing else will change behaviour. And I actually expect that will happen. Many people will be displaced and die in the meantime, which is obviously awful, but people collectively are completely fun with letting other people die and that's just the truth.
So for many things I just don't think it's as dire as many think.
But one area where I think we're in real trouble is the the resurgence of literal Nazism. This isn't a perjorative. We've come so far that the former Prime Minister of israel engages in Holocaust revisionism to blame it on Palestinians [1]:
> Mr. Netanyahu said in a speech to the Zionist Congress on Tuesday night that “Hitler didn’t want to exterminate the Jews at the time, he wanted to expel the Jews.” The prime minister said that the mufti, Haj Amin al-Husseini, had protested to Hitler that “they’ll all come here,” referring to Palestine.
> “ ‘So what should I do with them?’ ” Mr. Netanyahu quoted Hitler as asking Mr. Husseini. “He said, ‘Burn them.’ ”
We have the highest-ratest host on the #1 cable "news" network openly pushing Nazi propaganda [2]. Republicans are in love with autocrats and the examples are legion (eg Trump's praise of Jinping, Kim John-Un and Putin, GOP praise of Victor Orbon of Hungary).
As much as age has given me perspective to realize most alarm is overstated, I can't help but think this is going to end very, very badly.
