Bad apples spoil good ones. Teach your children to respect you. Part of the mistake parents make is not to teach children to respect adults. For example, by allowing their children to talk to people in any kind of way. Freedom of speech and behavior come with the sense of responsibility and accountability.
Children earn respect as they grow up from their parents.
There is no way parents should allow their children to run adults' lives. Parents who feel inadequate may want their children to run their lives because the parents feel inadequate. Perhaps they want to tell themselves they are doing things to make the kids happy regardless to whether these will help the kids in the future or not. Both parents must always speak with one voice. Well-educated and adjusted parents don't criticize each other before the children when the parents disagree regarding the raising of the children.
