I have mixed feelings. On one hand, all of us have to survive and find ways, no matter what life throws at us. If you can afford it, putting income protection insurance in place earlier takes care of this kind of situation.
On the other hand, if my child struggled and I was as rich as you think your father is, of course I'd want to help them. In fact, I do help support a child because there are good reasons for it and they have a medical condition that limits their work. But I do try to balance letting them be a responsible adult with keeping them as a dependent, because that's not actually in their interests either.
Rich is relative. My son thinks I'm rich because he's comparing to himself. The reality is that I'm not visiting my parents overseas because, while I could, if an emergency happened and I had to go right back, that would be financially challenging.
