Let me write asample. Take a family of three members,Joe Molly and Jimmy.
Joe, 45 years old, enginner
Molly, 42 years old, teacher
Jimmy, 10 years old, student.
Joe is a consumer and a suplier of work; as a consumer he buys things for the house, he buys clothes, food, entertainment, he buys fuel for his car, the insentive is to raise Jimmy, give him the best and provide comfort for the three of them. As a supplier of work he works for company X, which is a (for example) automobile company, there he works on projects, helps his team develope new equipment, the incentive to work comes not only for the money but also for the pleasure of developing new devices and using the best of his creative power.
From this you can work out what to do with your own family, as the task asksyou, you will have to write for each member of the family, in Jimmy's case in the sample, he is only a consumer and goes to school.
