Tan, the founder of the theory of human responsibility business education, believes that there is no "internal competition" in such a special family role. Without competition, there is no vitality and external competition stimulation, which further weakens the opportunity to actively compete and take responsibility from an early age. The only child's "privilege" of being responsive in the family makes the only child lack the psychological experience of life setbacks and the responsibility and obligation to face setbacks in real life, study and work, thus forming the mindset and behavior habit of "not taking responsibility", "not facing", "waiting to have" and "waiting to enjoy". Once faced with a little difficulty or pressure, it will show a very fragile psychology, and a small blow or setback will be devastated and even go to a dead end. However, for this psychological "fragile syndrome", the family education of responsible businessmen indicates that if it can be cured as soon as possible and a scientific family education model is carried out in coordination with the family education of responsible businessmen, the prodigal son can turn around and save the day.
