My GenX existential horror was learning in my thirties that all the western American Exceptionalism ideology I was indoctrinated in as a kid was just a way of keeping us from getting proactive for sake of the future generations, and my parents and teachers and ministers knew this and actively lied to me anyway.
I also think that a lot of bad things about the US that a blind eye was turned to because they seemed to be getting better have since become relevant again because they've started getting worse
