So what's a smell that suggests this is the case? According to the triple melting pot theory, in countries like the US, ethnic identity, under the tendency toward some kind of assimilation, gives way to religious identity as not only religious identity, but a substitute for ethnic identity.
So what happens with the waning of religious identity? Various dehumanizing ideologies start to look attractive. This explains both the appeal of the sexual, racial, and ecological ideologies that have become popular recently. These ideologies promise identity and social belonging, perhaps even an alleged higher purpose, which is to say they offer false and flimsy identities, ones that have political utility for those who control them. Various subcultures, many created by corporate interest around various products, do the same thing. You have "communities", so-called, that center around owning a particular brand of something. Corporate brand constructed false identities.
People don't know who they are. They've alone. They don't know the address of the destination, or even that there is an address. Their horizon goes only as far as satisfying their base appetites, and they pay lip service to ideologies to avoid being shunned from groups without which they cannot satisfy those appetites. And when they do, they discover that their satisfaction isn't all that it is cracked up to be. Here follows the realization that no hope is to be found in what has been sought. From here: suicide, or some higher realization.
