I feel that secure attachment to a parent or primary caregiver influences the well being of a child in the future. When a child has a secure attachment with a parent, then they use that relationship as an example of how future relationships would work. Bowlby argued this in the internal working model of the social work. I agree with the idea that if a child has a stable relationship with a caregiver then the child is more likely to be successful in future relationships, but I also think that environmental circumstances influence the future of a child as well. For example, education and traumatic experiences can also play important roles in development.
I agree with you that education and traumatic experiences are important. Traumatic experiences in particular will influence not only the child but also the mother, so that she may not have the time or emotional ability to be fully accessible to her child. And as important as such experiences are in themselves, the way the child responds to them will be even more important, as he learns how to solve problems and deal with emotions.
I agree with the fact that environmental setting that a person experience later on in life can affect his or her attitude towards a relationship too. For example, the traumatic experience can led that person to feel that relationship will not last forever and there is a possibility for incident to happen that separates two people in the relationship. This trauma will leads to an insecure attitudes towards relationship, even though the person had a very secure attachment in his or her childhood.
I agree with your opinion. Environmental and hereditary factors have a large influence on a child's future regardless of his relationship with his caregiver. Though having a secure relationship is a good start, it does not guarentee a good future for the child. There can not be a direct correlation between the two.
I definitely agree with the idea that education can play an important role in development, whether it is the caliber of education received or the environment in which a child learns. A "good" education can instill values in a child that they "must" attend a prestigious university or pursue a career with a high salary. An environment in which a child establishes a healthy relationship with teachers and peers can lead to both confidence in forming other relationships with people in other educational settings and seeking similar relationships outside of the school setting.
