In the average Black American community, there is endemic negativity in consciousness, mentality, mindset, outlook, philosophy, psychology, purview, & outlook. Many Black Americans have a passive philosophy towards life. They even have a dependency on varying levels. Racism only plays a very minute part in the majority of Black Americans not being successful in American society.
Many Black American parents don't take education seriously. They seldom appear at their children's PTA meetings. They believe that it is the teacher's job to help THEIR children w/schoolwork, not them. They refuse to be proactive regarding their children's education as opposed to other racial/ethnic groups who are very proactive regarding their children's education. They don't stress to their children a high level of success & achievement. They furthermore emphasize being social over being intellectual. This behavior is evident even among middle class Black Americans as I have witnessed such behavior first hand. Black American children who are more intellectual are told to "get with it", "hand out", & "be more like others". Have you noticed that the most popular Black American children aren't that smart while the smart Black American children are ostracized, even demonized?
Many Black Americans seem to be happy working for others instead of working for themselves. That is the dependency nature. They want others to take care of them & not assume any responsibility. In addition to working for others, they seem to be concentrated in lower to middle level positions-this goes even for educated Black Americans. I know one Black American male who refused promotions because he indicated that it would be too much of a hassle. Many Black Americans, including relatives, indicated that it is just TOO MUCH HEADACHE to assume responsible positions. So they remain in lower level positions where they have the least autonomy & ownership.
Many Black American parents advise their children not to reach "TOO HIGH" but to settle for middling. They seem to be afraid of success or that success isn't for them but for someone else. They appear to be comfortable with poverty or middling. They may even feel that they aren't deserving of socioeconomic success & the good things it brings. So they settle & teach their children to settle instead of aiming for the highest.
