I was also a kid in the 70s and while it did seem pretty gloomy then, I think people are gloomier about the future now.
> And even the re-emergence of some of the worst people (let's just aggregate them into "the racist shitheads")
In the 70s there were racist shitheads, but they were pretty afraid to come out into the sunlight. Now they're just out in the open. I think I liked it better when they felt like they had to hide.
The other thing about the 70s compared to now: it felt like pretty much everyone was on the same page back then. There wasn't right-wing news and left-wing news, there was just news.
