First, I think you and I would agree that education is very important, if not the most important criteria for getting ahead. This was realized a long time ago by a black American named Charles Houston, who fought to secure equal education for blacks. It is too bad that black students today do not take advantage of his hard work. I think your source is wrong. The problem is not discipline, it is the breakdown of the family.
Fathers are absent and mothers are trying to carry the load alone.
If black children could appreciate the difficult struggle of the early black pioneers, they would have a different attitude regarding education.
