How does a culture of fear change people?

I watch and wonder what motivates people a lot. I wonder sometimes if they are paying attention to the choices and effects those choices have on others in the lives. I'm curious how people negotiate and navigate through their daily lives and ignore one of the core motivators in the US....fear. Fear of not getting enough of whatever the current "need" is at the moment, not having the biggest house, biggest car, biggest bank account, extensive wardrobe, excessive number of shoes, more and more toys and games to feel safer and feel better about who they are and what they belong to. Fear of not belonging to a group or the right group, fear of others, fear of others different from us, fear of the unknown....fear is shoved down our throats and jammed into our brains and we aren't awake enough to say enough...bull shit...I'm not buying it. So what happens and how does fear change people? In the work place it makes people control communication and information, it makes people afraid to speak up and talk about the truth that is in front of all, it makes people abusive, inappropriate, bullies, jerks, and many many many with this mentality get promoted to positions where they are provided more access to promoting the culture of fear...and culture that permits us to frame the problem from one perspective, that of those in control. Fear keeps people from getting close, from collaborating, from finding solutions and support collectively. Fear feeds fears and starves our sense of community and care. When competition and the belief of win/lose is the only framework to live within, fear grows faster. When those who believe they are winning act in manners that they believe keep them winning, others are kept away from opportunities, acknowledgement, and a joyful life. It can't be like this everywhere on this planet, if it were we would have killed ourselves sooner than we will at this rate with the US impact on the globe. It weighs heavy on my heart and hurts to imagine the direction we are heading. The similarities between national, state, regional, local and work place politics are not a mistake....they are status quo. When will that be enough? When will shift happen?
