What I spend is someone else’s income. Apple co-founder Steve Jobs discussed every morning at breakfast with his family about buying a set of Miele washing machines and dryers from Germany for two weeks. Why? Of course, it was to teach their children about economics and to illustrate a lesson about opportunity cost, a common trait among wealthy people. If you buy this washing machine, you cannot buy that one. That is the opportunity cost. It’s a form of relative value, based on the idea that choosing one option means sacrificing another, so the value of each can be compared within those limits. Wealth begins with training in understanding even trivial opportunity costs. To succeed in business, you need to learn how to measure opportunity cost first, rather than just how to make money. - 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”
