From this incident, we must make this a lesson, especially for those who already have children. Educate and love your children sincerely, do not consider children as our investment (Later, when they have an income, they must "pay" you).
Perhaps this is not an incident, perhaps this is a lesson for parents on how to show their kids in action what "real life" is when they grow up and leave home. They will have to pay rent somewhere and have many other expenses... I think it is best learned through real examples... There are some interesting videos where a father explains to a child what tax is by eating half a cake before giving it to him, there are also some with hamburgers... he takes a big bite before giving it to him.
Children are not our investments, but we invest in them (in every possible way) as much as we can before they "spread their wings". We need to teach them how the world works, and the better we teach them, the easier it will be for them to manage tomorrow when they are adults. Don't get me wrong, I don't think we should charge rent to our kids...but this is an interesting way to explain to a grown teenager how the world works. There is no free lunch. I think that it's better to learn about "life stuff" sooner rather than later...
