Funny you should mention, measles is back, and worldwide fatalities is on the rise. And are you suggesting that US healthcare has improved in the last couple decades? Antivax efforts have made the possibility of a return of endemic polio possible since folks travel, and it's not extinct. Measles was on its way to extinction in the 1990s, but after Wakefield's fraudulent study and the partisan politicization of disease, a host of diseases we never had to worry about anymore are popping back up again. As child vaccination rates continue to drop, we will see it all again.
The adults by and large have all been vaccinated. The kids however are being treated like guinea pigs in an ideological experiment where the losers are the kids themselves.
And as a child of the 70s and 80s, yes, I personally remember the ever-present threat of nuclear war growing up. I also remember the teen suicide rate being abnormally high due to it. Kinda like the rise we see today. It takes its toll, and doesn't at all mean they're "soft".
