Yes, the Children Act, back in 1986 (?) started with the best of intentions. But, I suppose society has changed.
As you say, we have increased use of drugs, increased use of other things, and often, the result is a chaotic household.
Very young kids are carrying knives, others are becoming sexualised long before they are emotionally ready to be, and too many people want their own way, about everything, too often.
Resilience and common sense often seems in short supply, and I don’t know why.
We have more than any previous generation, there is more support, financial and practical, than ever before, and yet there are, apparantly, increased mental health issues, such as stress, anxiety and depression.
All this impacts on the care of children - so, no wonder SW’s, teachers etc. are struggling with the work and caseloads.
I don’t know the answer.🤷♀️
