If the child is making money then that child should want to help pay the bills, especially after experiencing what work is like. Otherwise that child is simply spoiled rotten. On the other hand, forcing a child that does not want to pay rent to hand over cash will not teach them the value of money, as many parents hope it will, and I think it is a misguided attempt at parenting.
I agree with this opinion. But if we think generically, apart from this particular case from the article, then it is of great importance in which country a similar life situation occurs. Since the local mentality towards the family is of overwhelming importance for assessing such a situation, and it can be completely different from one nation to another, even to the contrary in some aspects. So if we keep an open mind, then there can be no definite answer to this situation (in general, the financial relationship between parents and children), since all opinions are based on local customs and mentality.
