It's not about better.
If kids are entitled to get pocket money it's not in your hand anymore. You can't deny to supply them with money, not even as punishment. But parents are entitled to get help from their kids at home. Not as work but helping hand.
You - personally- might not agree. But it's about rights of children and rights of parents.
Normally it's not necessary to discuss this because in most cases there will be an agreement between parents and children.
Also, parents are not to beat their kids as punishment.
You see there are a lot of changes in the meantime when you were young.
