I was thinking this too. Dysfunction can disrupt childrens' understanding of the world. Causing mistrust, accepting / repeating violent and abusive behavior. Or causing cycles such as loneliness that compound consequences indefinitely. Not saying these can't be overcome but obviously some people don't make it.

I most definitely agree. I just typed a response further up this trail saying the first bit of luck is having good parents or a good parent. Some of my cousins believe success can be brought about through witchcraft. In most cases, it is, unfortunately, something they learn from their parents.
