The correct answer is sandwich
The sandwich generation is a metaphor used to describe the pressure between generations. It is a generation defined by middle-aged women, who care for both elderly parents and their children who are still dependent. This occurs in the face of increased life expectancy.
The children's lack of willingness to care for their parents will in the future lead to a greater number of elderly and careless parents. In view of this, public or private entities will be more sought after to provide adequate care to these people.
