Have you noticed that even a couple years before COVID in the U. S., that people's vibes were starting to change?

People always say COVID changed many people but I already noticed around BEFORE 2018 or 2019 that people's vibes were starting to be strange. People were more happy and into celebrations, etc but people became pissed off, not wanting to have much fun. And these are people of all ages, generations, etc. Something in the air or something?
