Phones and technology also get in our way and we as a society have become passive in parenting. The pay back when they are pre-teens is going to be painful. http://www.apa.org/monitor/2016/02/smartphone.aspx
And when they’re teens, and young adults, and older adults too. I think that misparenting & malparenting (and miseducation & maleducation) are to blame for a lot of our modern problems, e.g. school shootings (something which, so far as I can tell, essentially didn’t exist until the 90s, despite weapons being a huge part of American culture for over 200 years).
I don’t believe we should ignore technology, and indeed it offers a lot for parenting (e.g. phones could enable parents to allow their children more freedom, rather than being used to grant them less). But as a society we’ve not figured out how to use it wisely yet.
I also think that we’ve deliberately ignored the lessons of the past and of other cultures, but that quickly becomes an entirely different discussion …
Columbine?
The Urban legend is not that it is a modern thing but it is the frequency. https://en.wikipedia.org/wiki/List_of_school_shootings_in_th...
We had school lynchings, though.

The problem with that is that teaching kids how to do human tasks is basically the definition of parenting. You're correct that many parents don't parent — but that's a problem which needs to be solved.
