It does seem to be true that parents teachers have lost the authority they used to have, especially in the eyes of teenagers. They are no longer seen as behavior: hard work, politeness and other positive qualities are seen as old fashioned. Many young people have no respect for these qualities or the people who represent them. In fact, I think when young people today are so rebellious that it's possible that both parents and teachers are afraid to exercise their authority. However, I do not agree that this is the basic reason for the increase in teenage violence.
While I believe it is true that a lack of social and emotional learning contributes to the problem. Other factors are surely involved: economic factors, for example. If a child comes from a poor family and they live in low-quality housing area, this is sure to affect the child, however loving the parents are.
There is also the question of . I believe that when you are in your teens your friends have more influence on you than your parents or teachers. At that age, part of a group, or even a gang, and this might lead to breaking the law in a number of ways.
In conclusion, while I of social and emotional learning from parents and teachers is a factor in the growth of teenage violence, I do not believe that it is the only or main cause.
