I think that I read years ago in a book called "The Secret Trauma" that in some study of a lot of girls and women abused as kids showed a lower average academic achievement and earnings than non-abused similar people. This book is from 1987; there are probably other studies out about other types of trauma and men too, by now.
My specific abuser has not achieved academically or professionally much at all; however, I remember that he was abused as a kid too, so it's not a comparison of an abused person vs. a non-abused person.
I thought as a kid that the way he was interacting with people essentially got him short term benefits but he wasn't going to get far with being abusive, manipulating etc. It's true from my perspective, but obviously not his... and he blames others for all his lack of "success" too...
I tend to think of these things in terms of taking responsibility for your own sh&t and not putting it on others in some manner; Patrick Stewart's latest character in an X-Men movie (of all places) had a positively wonderful statement about this concept and he just stated it so brilliantly. He watched his dad abuse his mom, you know, and tried to protect her as a kid.
It's often painful to take responsibility for your own stuff; being willing to face that pain (honestly) yourself, as you are able, and not put it on another is the key action, I believe. We all fail some, we all hurt people accidentally sometimes, but it's a sort of commitment to work on this and do our best, that I sense differs among people that I trust a lot and don't trust much at all, a "walking toward the light"...
The thing is, facing these things that happened to us is horrifically painful. Abusing someone else to get a momentary sense of power, when maybe the abuser is hiding from their own pain in a deep twisted way, seems to me to be where a lot of this stuff starts, and the cycle just keeps going.
So, perhaps we could honor everyone who is really trying to own their own pain in this way and be responsible for how they treat others (and themselves!!!), no matter what else they accomplish, and even if one never becomes totally "normal" (like most of us never get "normal"):alien:.
