I agree with the view that if women are not treated well, then any type of family (whether joint or nuclear) is not good. Most often bad treatment of women starts due to husbands who do not have backbones, who do not believe in the rights and happiness of women, who are mouse outside their homes, but turn lion when inside.
However, joint family will be way to go if men are committed and would go to any length to protect their wives and children from other not so wise family members.
