Having actually worked around troubled youth and seen literally 100’s of children move through the system, I don’t think you could be more wrong than you are. Prior to working with troubled youth I assumed it was more like 50/50 environment/genetics. I’m completely convinced it’s almost entirely environmental. In nearly 100% of the cases I’ve seen troubled children, they had parents that were doing something profoundly wrong. Whether it be neglect, violence, sexual abuse, etc, there was always something extremely concerning. I think it is actually incredibly rare for a child to end up severely messed up without extreme “help” from the parents getting there.
