One advantage of a joint family system is that it provides social support for struggling family members, yet there can often be no personal responsibility taken. Joint family systems are common in traditional cultures where family is valued.
The joint family system is very rarely practiced nowadays, particularly in western culture. As family members come from the same bloodline, it makes sense that a family would want to live together. A togetherness can be displayed in a joint family system because everyone helps each other and strives to reach the same goal. If a family member is going through hardship, then the other family members are on hand to care for that person. The family acts like a support system for those who are going through a tough time in life.
On the other hand, a joint family system can have difficulty functioning because there is very little freedom or individuality. Younger family members are expected to conform to the wishes of their elders, and this can be a problem if two generational cultures clash. Furthermore, there is little incentive to work hard since the rest of the family is expected to pick up the slack. A joint family system often results in poor living standards because hard work is not encouraged.
