I assume that you are asking us to comment on this statement. There are disagreements as to the efficacy of spanking in the United States today. Traditional parents say that spanking is necessary as a way to instill discipline in their children. However, most research today indicates that this is not true. My own view is that spanking is not an effective punishment.
My main reason for saying this is that it sends a message that is not an ideal message for parents to be sending. It sends the message that violence is a good way to get other people to do what you want them to do. Further, I would argue that it teaches children to be motivated by fear, not by any more positive factors. This makes it less likely that kids will learn to control themselves in the long term. It makes it more likely that they will do whatever they want to do when they are in a situation where they cannot be caught and spanked. This is not a good way of teaching children to regulate their own behavior.
