But that's just punting the original question. Obviously parents aren't getting better, they are getting worse. Why is the question.

* Social media (Echo chambers, propaganda bots, algorithmic content designed to get attention and emotion)

* Lowered attention spans

* A general reduction in critical thinking - instead preferring headlines, summaries, and easy answers

* Increased partisanship

* Reduction in third spaces and community connections - people becoming more isolated

* Financial stress

I'd say those are the main points. They apply in almost all developed nations, to varying extents.
