This is popular in industrial cultures, but it is not the most frequent form of family in the world, despite the fact that it is becoming more common as technology advances. For example, about 30 percent of American households are single parent homes. An industrial family is a term used to describe a family business where one spouse works while the other stays at home with the children. This was very common in earlier times when women were expected to stay at home and care for the household while their husband worked outside the home. Today, this is still common in some countries including India, although it is beginning to disappear as women get better jobs and don't have to stay at home. In most cases, the owner of the business decides how many employees they want to have on their team. If there are too many people involved in running the business, it can lead to problems with conflict over power and authority within the family. For example, if the wife wants her own job so she can quit her husband, this could cause problems for the family business. Her husband might not be willing to give up his role as head of the household since this is what has always been done in these types of families. He might even try to force her to stay at home until he finds another way around it.
