What is stunning is the dismissal of causation. But, tied shoes and nutritious snacks don't nurture souls. Children commit bizarre, callous acts because the adults in their lives treat them callously, in warehouses with lots of perks and stringent government regulation. Parents who care enough to draft and lobby, just not change diapers. There are two levels of parenting.
Epidermal parents are what most children have today.
Epidermal parents provide for their children, have pictures of their children at work, kiss them good night and even prohibit sugary snacks. On the weekends, epidermals do fancy outings, lessons and sports. Nothing is too good for their children and no expense too great except time and career. Epidermal parents are hesitant to discipline because they don't want to spend limited parent time at odds with their children. You haven't reached the other level of parenting, subcutaneous, until you are sticking your tongue out at your child behind his back.
