I think, as a society, we’ve moved on from, what would now be seen as, abusive kinds discipline, and we’ve completely changed the standards of behaviour we expect from adults. We’re literally operating without a playbook, with no idea of what we’re trying to achieve or how to set about it.
There’s also a tendency to confuse respect for personhood with a belief that everyone thinks like me. So with the best of intentions, people treat children like miniature adults, without regard for their developmental stages or needs.
Currently the loudest cultural influence is from
psychologists - not promoting wider education about developmental ages and stages, but warning of the (lucrative) dangers of mental health.
We’re living in fear of anxiety and mental health problems. Which is probably quite similar to how our ancestors lived in fear of sin and eternal damnation. We’ve just switched out church authority for psychology.
And psychologists aren’t bound by a Hippocratic oath, and while at the highest levels there are efforts to promote evidence based therapies, it isn’t a well regulated profession. Some therapies are ineffective, or actually damaging, but that’s not widely understood. Yet most people think of therapy as a the solution to all mental issues, like a course of antibiotics for the mind.
The pharmaceutical industry plays a role too - the idea to medicalise ”generalised anxiety” was brilliant. We can no longer distinguish ordinary stress, and existential angst from psychiatric disorders and we’ve pathologised normal human experience, because it makes money to do so.
