From what I read in the article, the child is not directly paying for the rent; the mother is just asking her to pay that amount every month in order to support the family.
You are right, that was why I stated clearly below my post that the write-up is not exactly what happened. I added rent to it because it's part of household bills.
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 thought about that, the child should choose how to spend on the household. The monetary contribution shouldn't be a rule. Allowing her to take it upon herself is much more helpful than forcing it on the child. It'll also be a relief to the parents to see their child taking up responsibilities without being reminded or forced. Sadly, some adults wouldn't take action if their parents don't put the bills on them.
