Homework is a class issue. In school everyone is equal, but at home some people have advantages because of their family background. Middle-class families with books and computers will be able to help their children much more than poorer ones can. This can mean poorer children end up with worse grades and more punishments for undone or badly done homework. David Baker, a researcher, believes too much homework causes parents and children to get angry with each other and argue, destroying the child's confirmed fence. On the other hand pushy parents may even end up doing their kids homework for them-cheating and not helping the student learn at all.
