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”
Vaccines have allowed people to travel worldwide. Migration and population density are benefits of vaccines. When vaccines failed to curb the epidemic, the “space” ultimately addressed the epidemic. This history is why maintaining “social distance” is essential. Hunting requires one million square meters to secure a person’s livelihood, but urbanization restricts many individuals from accessing such vast spaces. On the other hand, if agriculture can address livelihood needs with just 500 square meters, and its efficiency can increase by 2,000 times, then the perspective on the epidemic reveals insights about civilization. - Joseph’s “just my thoughts”
