Without going into the argument of the ‘class divide’, this question, to me, underlines the crucible of the concept of class advantage. The middle-classes uphold this assertion of yours firmly, and children are thus schooled, so that they are challenged, exposed to inspiring role-models, taught adequately, pushed, encouraged and disciplined, to forge a character and acquire self-belief and an equipped mind to gain confident self-belief and self-assurance. On the other hand, and I do straight away, accept my generalisations, the Estates youngsters, have no such influences, due to obvious factors, they experience no such aforementioned breeding. From the beginning, they are confronted with meagre opportunities to grow and thrive, given little challenges, inspirations or responsibilities, results, we breed the Yobs and the Chavs. Fact:- an under-developed brains in prime physically lethal forms, and innocently wonder at the alarming levels of crimes in our societies. The difference is very obvious to me. Your question is very intelligent and my somewhat simplistic answer, is that, its evident to understand that, if children are tuned in to positive influences, from the onset, positively predictable results could be expected and vice-verse. True sustainable confidence, acquired from tested results and achievements, definately promotes self-esteem and great self-assurance. Standards must be sustained and encouraged and positve bounderies challenged at every turn. But I do appreciate that political realities makes these issues more complex, than we have the time and space for.
