What does the population crisis mean? Is there a possibility of a population crisis in China?

The capitalist system is the root of the population crisis. The population crisis is the deterioration and aging of the population structure, and the negative growth of the labor force aged 15 ~ 45; The fertility rate is declining rapidly; The number of women of childbearing age has decreased rapidly; In other words, under the capitalist system, most people are slaves of capitalists. They were oppressed and exploited by capitalists. They work hard every day (capitalists extend working hours and let workers work for them quickly), with low wages, high house prices, car prices and medical expenses, high school expenses for children and high prices. Moreover, due to the pressure of work and life, the broad masses of people are unwilling to have children and dare not. As a result, young people don't want to get married, and they don't want children after marriage. The proportion of only children among modern young people is very large, and many of them are only children. In today's society, housing prices, medical care and education have led to many singles, leftover men and women, and married people. That makes sense. Advances in agricultural technology, medicine and other aspects have extended the life span of human beings, the elderly population has increased rapidly, and there are few newborns, forming two extremes, so the population crisis does exist. Husband and wife should support their elders, husband and wife. They must support their elders-parents, grandfathers, etc. For couples with only parents, they also have to raise four children. For couples with grandparents and older elders, not four people, but a bunch of people. If they have brothers and sisters, then their elders can have brothers and sisters to support them. There are also some young couples, as wives, who can't work when their children are still in infancy and have to look after them at home. If parents are young and healthy, they can leave their children to their parents for care, and their wives can also go to work and go out to work. If their parents are unhealthy, sick or old (old age makes them weak), wives can't go out to work. In this way, the burden of the whole family falls on the shoulders of a husband. It can be said that in this case, their life is difficult. After the children run away after the meeting, both husband and wife can go out to work and take their parents with them (parents need the support of their children when they are old). However, this is impossible, because first, if they are not only children and have brothers and sisters, they support their parents with their brothers and sisters, and they and their brothers and sisters need to support their parents because their brothers and sisters can't or can't. At this time, they and their brothers and sisters will ask their brothers and sisters to leave a person at home to serve their parents. Second, it is impossible to support parents and children outside: due to the high prices of rent, vegetables and so on, coupled with the large number of people, coupled with the extremely high tuition fees and low wages for children to go to school outside, they dare not take their parents and children to work.
