The first humans the children are compelled to bond with, the parents, are the source directly or indirectly. And most kids are exposed to it. And too, most kids seem ok. No bond is formed. Without human bonding beyond the umbilical chord, the kid is a two-dimensional monster lacking empathy and having no regard for anyone.
People become mere objects, useful or disposable.
Anything that goes into their minds from time of birth to a certain time later in their lives is what the parents put there, or allow to be put there. There has been something wrong with the proper function of this process and the society that has permitted it to go astray. That becomes more clear as society has increasingly complex problems with radically demonstrative youth, guns and violence. I mean, kids always were demonstrative. That's not the issue.
