I was 20 in 1991 in Europe. I was flying regularly without any flygskam. The USSR was just falling and we were all sure it was an unmitigated good (we still didn't know that the Russians will die by scores and see their life expectancy drop like a rock); Germany was just reunited and we thought the EU was a great project, not a bureaucratic monster working for the oligarchy; Hell, I even believed there were nice guys and bad guys in the Yugoslavian wars. I probably even believed that voting counted. Future was bright, and open. Year 2000 was still ahead, with its wonders.

My mother was 20 in 1968, and it was the good old days. They believed the revolution was around the corner. Present was somewhat grim, but future was bright; in her years of political activity she saw the pill come, abortion rights, women rights enhanced, the end of dictatorships in Spain and Portugal, the end (in civilised countries) of death penalty, the crumbling of USSR.

My children are in their 20s; my son refuses to learn to drive because cars are evil and he doesn't want to own one, ever, because they're bad; he's hell-bent of enjoying the now because he's pretty sure that there is no future, except climate catastrophe, incessant wars, and electronically-enhanced surveillance; he thinks that democracy is a complete scam and he forgets to vote if I don't nag him weeks in advance. He's just as disillusioned as I am, but 27 years younger.

So I think the picture is more complex. The global direction of evolution is much more important than the objective starting point.
