Some people may mention that the extended family has been is important to maintain family`s value until the present. in the past as well as today. However, the family members should had to spend a lot of time together on maintaining family economy in the past. Also the modern world demanded demands family members t work working separately to each family member.
First of all, the family member should had to (과거에는 그래야 했다 ~) spend a lot of time on maintaining family`s economy in the past. In the past, every family member should had to work together to continue their lives life. Thus, fathers, mothers, brothers and sisters worked together simultaneously, relaxed together, and dined together. However, today parents both both parents work and their children study in school on weekdays. Also parents often come home late and children are busy studying their study and doing a part time job. In addition, they relax relaxed separately on weekends. Parents watch TV while, children play a computer game. So they have few chances getting together. Such circumstance lessens the oppornutity for family members to get together and thus makes the rold of the family less significant.
Second, the modern world demands family members to work demanded working separately to each family member. The modern society consists of many parts. Thus, the society needed to work separately. In fact, each part is managed independently in modern society. Naturally, family members also have their own working area. Commonly, fathers work outside, mothers work in home. Their children study work at school. Thus, they had a have only little time to talk each other and even when they have a conversation, they do not have much in common to talk about since they work in separate divisions. the extended family`s value which worked and relaxed together have a difficulty keeping in modern society.

It is because the family member should spend a lot of time on maintaining family economy in the past than today.This is because the family members do not work together for the family economy anymore. Second, Moreover, people work in specialized fields, so the family members do not have much in common. the modern world demand working separately to each family member.
