This is due to the misbehavior of parents who are not good at raising and educating their children. Excessive pampering of wealthy children and the ease with which they obtain everything with complete ease will make them ineligible to bear responsibility themselves and will lead to their bankruptcy after the departure of their wealthy parents.
So the blame is primarily on these rich parents.
In my opinion, it is natural for parents to spoil their children because it is the right of parents who want their children to be happy. It's just that if they are spoiled excessively of course it's not good because it's likely that later they will depend more on their parents, by never having their own responsibilities, and of course this is not good.
I also don't think I can blame the parents entirely, because it's a common thing for all parents. If the children have a good mindset, maybe they can reject the spoiled actions of their parents and learn to be independent. So if they themselves have their own sense of responsibility I think they will learn everything independently.
