I think you're probably vastly discounting the amount of childhood neglect wrought by social media addiction on both the parent and child's parts.
The median child of a social media user (so basically, the median child) is vastly more well off than the median child of a heroin/crack cocaine user and its not even close.
The fact you're suggesting some level of equivalency is wild imo.
Glad I could draw attention to the irrational logic of the current "social media is evil" moral panic.
