Sometimes too, it might not be that the children doesn't want to take care of their parents but the question is, are they themselves financially stable enough to be able to extend a helping hand to their parents or anyone else? Maybe the son doesn't have enough to sustain himself before thinking of the dad or perhaps the wife have turned them against him. Parents have needs to also plan for their own future after retirement or in case of any bad situation, so that they will still have something to fall back at.
If you think that only when you are financially stable or rich, you will think about repaying your parents. I bet you will never repay your parents because you can't be sure when you will be rich and whether your parents will wait for you until then. To me, personal finances are not a reason or barrier that prevents us from showing filial piety to our parents. Because parents don't need you to give them a lot of money, what they need is for you to be there for them no matter what happens.
Through this story, we are reminded that we should always have a backup plan for ourselves instead of thinking that we can rely on our loved ones. But I will not lose faith or doubt my loved ones because of this story. The world will have this person and that person and the man in this story is just the unlucky one.
In my village and those 3 people are my close friends. Their father is sick and bedridden but his wife and 3 children have taken care of him for more than 15 years without a single complaint. They were willing to sacrifice their youth to take care of their sick father, which shows that not everyone is as cruel and heartless as the wife and children in OP's story.
So like - the debt to parents can never be repaid. Bitcoin doesn’t replace the human obligation to care for one another, especially for our parents. It's true that many in the world struggle just to support themselves. Yet I’ve seen people with very little still do everything they can to care for their parents —sometimes just with time, words, or just like being there. That’s more meaningful than money.
