Have you noticed that around the mid 2010s', many people here in America started to look more depressed, dead inside and kept getting worse?

I have noticed how many people before that weren't so angry, depressed, dead inside, being like a zombie. After it started, it got worse, and then during Covid, to now, it got so bad. People snap at anything. Get in shouting matches. Is it because of the economy, working too much, everything being expensive, etc? And than Covid to present things got worse with that?
