I think narcissism is rising in western society. And it seems people are insecure for roughly all the same reasons, which leads me to believe it must be global media platforms that are "teaching" people where their insecurities "ought" to lie. This is why you're getting "normal" people too, as a very real concept, which technically, shouldn't even be a real thing as every human is an individual.

By pointing out "shortfalls" in people, you automatically create a drive in them to "match up", which is a very cunning way of getting people to play right into your ideals and control them, and get them to follow you.
