The above can leave human beings in a very fearful place.  I see that our needy self which relates to early attachment and dependency as the begining of our creation of fear.  This is because we were totally dependent on others for our survival.  This begins with a need for human contact, soothing and feeding.  Our search for certainty and control in a world where we may have felt  scared because we were not always successfully soothed or fed straight away can be experienced  as hostile to an infant. This because we are association annimals.  In other words all our experiences impact us because of our emotionality and level of consciousness.  These experiences are then carried over.  It  is transferable from our past script experiences to our present life.  You only have to look around society to see how people from all sorts of walks of life strive for some power and control.  This is from gangs on the street to business and deals of one upmanship.  On some level much is all the same and emotionally driven as a way of making ourselves more comfortable, important , validated and life then seeming to hold some meaning.  By definition powerlessness is about being without the ability, influence, importance, strength, impact , control and status.  All of these come in a multitude of different and diverse forms.
