Хороший перевод на русский. Только не с переводчика!

Who says that school is work. It's not work at all ! We don't have to do what our parents have to do in their jobs. We have to learn and that is all. People who work produce something or do important things for other people. What do we produce? Nothing. When people work, they get money for their work. And we don't. There are some pupils who get money for good marks from their parents. But they are few. So... Who is right, Mike or me?
