Mr. White: Young children, perhaps some boys, stay at school until they're eighteen or nineteen. A part-time job can't harm them. In fact, it's good for them. They earn their pocket money instead of asking their parents for it. And they see something of the world outside school.

Businessman: You're quite right. Boys learn a lot from a part-time job. And we mustn't forget that some families need the extra money. If the pupils didn't take part-time jobs, they couldn't stay at school.

Editor: Well, we have got two for, and two against. What do our readers think?
