There is a great, great book, Bad Therapy: Why the Kids Aren't Growing Up by Abigail Shrier. It is focused on one, but probably the most significant factor, which made the rising gen-z extremely infantile and unfit for life. It is the pervasive "therapy culture", which has invaded every aspect of our lives. It damages everyone, not only gen-z, but kids and teens are especially susceptible to this "virus".

One can ask the next "why" question. Why has this pervasive and damaging therapy culture become so popular in Western societies? As you said, Harold, there are many factors that lie at the root, and one of them is the very nature of capitalism, i.e., making money by all means, including by making things worse, knowingly. There is a huge army of certified (and not certified) jobless "experts", of all those psychologists and psychotherapists who need paying customers, so they invent more and more reasons to pathologize normal human conditions, dispensing diagnoses liberally, including through social media.

It is sickening what they are doing, but the clueless parents are eager to pay for damaging the mental health of their kids. And if it was not enough for those charlatans to charge for their "disservices", they also put healthy kids, as young as 7 years old, on psychotropic medications without thinking twice.

"No more phone calls" is only one small facet of the damage done to the young generation by the parasitic pervasive therapy culture.
