Basically sometime around the 00s-10s, seemingly everyone decided to become a massive dickface with zero concept of social cohesion, and it's just me me me me me me, and fuck everyone else.
Society needs a reset, pretty much everyone has just become vile, angry and inconsiderate / extreme main-character syndrome.
We shouldn’t be surprised society has fallen.
In the real world things seem to be pretty much the same as they have been for most of my life (and I am 60 in a few months).
Online, yes some people behave like monsters and occasionally some of that bleeds across into the real world - but overall I think we are pretty far from saying that "society has fallen".
