Not surprised. They live on credit and the idea that they’re entitled to whatever feels good for the moment. They are unable to think ahead and anticipate (or avoid) the consequences of the choices they make today. To them, saving money for the future is unnecessary. They expect mom and dad and/or you and I to provide financial assistance when they need it.
