What I am suggesting is that what is happening is schools and what is happening outside schools ie in what I am calling the wider community all are linked to a common cause or trend in society.

That is, of course, different from a causal relationship between each other.

 

In that case, I think the timing is a bit off to be linked. For example, the number of a full-time mothers at home was the lowest around 2000 and then increased or kind of levelled off and even increased a bit in the US around 2012 (probably fluctuated since then, I don't have the latest numbers https://www.pewresearch.org/social-trends/2014/04/08/after-decades-of-decline-a-rise-in-stay-at-home-mothers/). Some other data also suggest just some fluctuations around 2000, though there were also more stay-at-home fathers, to compensate.

However, what we see in terms of education was most dramatic starting around 2010ish and only accelerated (so basically after decline had levelled off or even reversed). Some folks have suggested that the timing fits the increase in social media, but of course these are mostly correlations. 

Found an interesting poll on K12 educators in the US. It is only a snapshot and I have not looked whether there is temporal data available https://www.pewresearch.org/social-trends/wp-content/uploads/sites/3/2024/04/ST_24.04.04_teacher-survey_topline.pdf
