In an organised society the roles and status of people are defined and fixed. Their functions are well defined and they carry on the tasks allotted to them. They enjoy the status in accordance with their role in society. A primitive society suffers less from disorganisation because it is stable and its members follow the professions allocated to them.
But in course of time our norms change which also brings a change in the roles and statuses of the people. They no longer are treated as fixed and the people begin to choose from amongst the different role which causes disequilibrium. Thus the women are no longer confined to homes.
