It is often said that many children are more blessed. Originally, it was good to have more children, but the premise was that the children's educational level, correct outlook on life and gratitude. First of all, the family burden, and now the society is extremely rich in material things, which also leads to the high cost of raising children. Many working-class people can hardly afford to raise two or three children (many people say that giving birth to one is also a health care student, and two are also in a hurry, and those who really dare to have children are absolutely effortless); Secondly, on the issue of education, it is difficult for most working-class people to take care of their families and careers, and they have to devote most of their time to their work. The reason is simple: more and more only children have become the backbone of the family, with the old and the young, and no brothers in the middle.
