A joint family (an undivided family, joint family, extended family system) is a large undivided family, where more than one generation live together in a common household. A joint family is a form of family where grand-parents, father, mother and children are united together under one roof.
In such families, the son does not distance himself after getting married. Instead, he lives in the same house with his family and his family with his wife and children.
The eldest male member is usually the head of the joint family. His power and functions are like a trustee. He is entitled to take economic and social decisions on behalf of the family.
The benefits of a joint family can count more than one can.
It is the best way of life that is most conducive for development.
It is based on the principle of proper economy. It considers it a law of creation that not all men are equal. Naturally it imposes a kind of unwritten discipline that those who are more financially capable will share some of the burden of those who are not.
Combined mace, naturally, operates on an understanding of mutual adjustment. Naturally, those who benefit from the generosity of others are grateful and thankful. Similarly study groups of boys in a large joint family are formed according to their age match. Naturally the cousins ​​study together, play together, quarrel together and even get punished together. As a result there is a sense of harmony in them which is free from any discrimination compared to being full brother or cousin.
The groom becomes a concern for all the elders in the family for married girls in marriage. Even if the daughter of a junior brother is chosen by someone because of her beauty or talent, he will not agree to her marriage until her senior cousin sister is married.
The basic needs of all family members are taken care of. Each member is guaranteed minimum subsistence to survive.
It supports all family members. Old and elderly people are respected. Proper care is taken for old, widowed, physically weak and disabled family members. Subjects such as this have imposed themselves on their members in a joint family. The head of a large family almost becomes its patriarch if the family and other constituents are looking after the norms well and healthily, the family of the family will expand.
Finally, a sense of unity prevails in the joint family system.
This often creates parasites that prefer to feed on the income of another and exploit the wellbeing and theoretical behavior of their partners. Sometimes some devious member of the family conspires to torture and exploit another innocent member of the family. High-earning members often insult low-earning members.
The cost of education has increased. High-earning members often want their children to study in expensive schools, but they do not want to share the burden of the children of other family members. In large families, the most important decisions are made by the head of the family. Since, not all individuals in the family have the opportunity to participate in major family decisions, they are often lost or develop a sense of inferiority complex.

The separation of families was evident from the joint families themselves. This is when the spirit of generosity, charity and sympathy is not balanced by strong moral line, character and foresight. If members remain for each other, then joint family can be successfully run. The suffering of solidarity and selflessness is the essence of joint family.
