Young adults solipsists? Hmm, I disagree with it, since in order for them to be solipsist they should be aware in a first time of their own existence and then come with the idea that they are the only one around and the rest is merely an invention of their mind.
No, young adults, (and most people), are merely egocentric, people got a tendency to feel they are unique, when they are not.
That would be the difference I believe. egocentrism rather than solipsism.
The belief of being unique and 'better', quite amusing in my opinion. At the end of the day, those young people in msn, chatrooms, social places, etc, feel quite comfortable with themselves believing they are 'cool' or smart. They satisfied with the way their lives are. Maybe because they cannot see beyond their own life. They don't try to understand their environment, (their surrounding).
They are too busy following trends, buying i-pods, video games, dvds, clothes, food, accessories, etc.
They are too busy following a path imposed by our modern society in which we are just making the rich richer and nothing else.
