Why does China's concept of raising children to prevent old age gradually fade away?

There is no doubt that children are the crystallization of husband and wife's love. Children are born because they want children and like them, not as a tool for their future pension. As long as the husband and wife are loving, the family is harmonious, and the children are properly cared for and educated, the children will be "good and filial" to their parents in the future. Before 1950s, most elderly families were families with many children. The purpose of having more children is to respond to the call of the country and contribute to the future economic construction of the country. Old people don't think too much about support, because the concept of raising children to prevent old age is deeply rooted in the hearts of old people around the 1960 s. The pressure of providing for the aged in families with many children is much less than that in families with only children. The elderly can be taken care of by their children in turn, and they can share the cost if they hire nursing staff or live in an old-age care institution. The post-70 s and post-80 s groups are mostly one-child families. With the rapid development of the times, children have been unable to take care of themselves under the dual pressure of work and personal life, and it is more than enough to take care of their parents. With the influence of aging and declining birthrate on China's pension structure, some elderly people began to give up the traditional mode of raising children to prevent old age.
