I think this problem basically does not exist in the one-child family, because there is nowhere to shirk the responsibility. Most of these cases are families with many children.

In today's society, the phenomenon of taking money as the center is really serious. In addition, many young people work outside all the year round, are self-sufficient and don't think about their old parents at home. The main reason is that the society is generally lacking in morality and is too materialistic.

If the old man has a fortune, his children will scramble to pay tribute to him. Only in this way can the elderly get a fortune after a hundred years, but in fact, many elderly people, especially those in rural areas, don't have much money, so their children refuse to support them. They think this is a thankless thing and a loss.

In addition, it is not excluded that the elderly are eccentric in the process of raising children. In this way, children who feel that they have not enjoyed much since childhood will think that the elderly are biased towards whom, and the children are separated, and the elderly should naturally be supported by whom. In particular, if the distribution of children is uneven when they are separated, those who get less will naturally be unwilling to support the elderly, while those who get more will think that everyone should support them together, which will lead to no one to support them.
