What does the farmer mean when he says, "The eldest is stupid, the second is immoral, and every family has its own problems"?

This sentence means that the boss is simple, the second is slippery, and the third is more than the boss and the second.

Poor living conditions, sensible since childhood.

A friend's family has three brothers and sisters. Because the living standard is a little worse than others, as a sister, friends have always been more sensible, and if there is anything delicious, they will give it to their younger brothers and sisters first. Once there is any dirty work at home, it is all my friends who carry the heavy burden to complete it, and because of economic conditions and other reasons, she finished her studies early. Perhaps all this looks silly to outsiders, but in her own view, as long as her brothers and sisters live well, it is worth it.

The elder sister is simple, and the second sister is glib.

Compared with the simple sister, my sister is more provocative and clever than her. She often praises her sister and is better than herself in dealing with people and things. The reason is actually very simple. Because I am old, the financial burden of my family falls on my friends' shoulders, while my sister has no burden on her shoulders because of her relative age difference, but she understands the life at home very well, so she still does.

The third child in the family is a pet.

Compared with the elder sister and the second sister, the younger brother at home is undoubtedly much happier. There are two plans to take care of him, and he hardly suffers anything, let alone reach for food with clothes. Therefore, compared with the elder sister's simple and honest childhood, the second sister refused to suffer, and the third sister was more overbearing and courageous than the second sister. There is no way to make him the pride of the whole family.

In fact, like families with many children, bosses are generally more sensible and it is not easy to know the living conditions at home, so they usually try their best to improve their lives with their parents. The pressure on the second child at home is relatively small, and the third child at home is loved by the whole family, so the style of acting is definitely different from that of the two sisters.
