Every child who has a sense of responsibility will think longer and be useful to his parents as long as he is able to help with whatever is needed without having to deposit money every month. If the child lives with his parents without any strings attached, he can lighten the family's economy by paying for electricity and PDAM bills.
I really agree that this method can help parents in this difficult economy rather than going out on their own, maybe the calculation is more than that.
Agree, we have discussed in another thread that discusses children as future assets for their parents, every successful child is obliged to help their family's economy because parents have financed all their child's needs from infancy until they are adults, all the sacrifices of parents can never be repaid with anything, so even though parents do not determine the rental price or ask for help to pay electricity bills or others, do it immediately as a step to appreciate them while you are still under their care, do not count your losses with your parents but make them happy with your success.
