Sadly, I think psychotropic drugs are a common denominator.
Yep and empathy is largely something DEVELOPED and taught; not innate. If the child is not TAUGHT empathy for others he most likely will not have it. If the child is not TAUGHT to stop throwing tantrums, (today “diagnosed” as oppositional defiance disorder—I kid you not) then he will continue to have a self centered toddler’s mind in an adult’s body. Shield said child from natural consequences of his/her actions (as is SOOO popular today; blame anything and everyone EXCEPT for Junior) and “med” him/her up and you have a disaster on your hands.
