The book seems to generalized the idea of parenthood. The cultural background and society does play a role in upbringing of a kid. I believe this book has taken a nuclear families as reference. And excluded the extended/ joint family
I am not saying one is better than other but both have pros and cons. I haven't read the book and this is a speculation based on your post.
But I am totally with you on the point that society is toxic as sulphur mine. And social media is just a dump ground of toxic waste.. Affecting the mindset of the people. Imagine someone who has been feeding off on the sm content.
....Really sorry for ranting here.
