One of the key principles of money is ‘opportunity cost.’ It means that when I buy something, I have to give up something else in return. We think we buy because we need something, but we often forget that we could buy something else instead. We rarely consider ‘opportunity cost’ when making a purchase. We do not compare other values against our needs. Buying something means giving up something else, but we often don’t realize it. When we spend money, we should also consider the ‘opportunity cost’; yet, in reality, we aren’t trained to do so. By making a purchase, we bypass the value comparison that may not offer any additional benefits. Maybe it’s because we lack knowledge, or perhaps the idea isn’t appealing. - Joseph’s “just my thoughts”
Before the high level of civilization, human life was tribal. However human beings were needed for the large-scale labor force for industrialization, so people were gathering in the cities for a living. That was the detribalization. These days when we are developed by social media, people are used to selectively make a relationship with those who have similar philosophies and preferences. Rather, the new media makes the retribalization in different meanings. Therefore, now human relationships are becoming more important the interests and preferences. When choosing to make a relationship, people gather according to their preferences. Communication is narrower and more easily ostracized. - Joseph’s “just my thoughts”
