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”
Regardless of your earnings, spending is inevitable. Therefore, spending holds more significance than merely earning, and wealthy individuals emphasize teaching their children how to allocate money toward education. This highlights that human emotions and desires are central to economic theories. Spending can be categorized into two main types: “consumption” and “investment.” “Consumption” refers to expenditures on necessities or perishable goods, whereas “investment” involves acquiring assets aimed at production. Without grasping these distinctions, money spent may be seen as a “waste.” - Joseph’s “just my thoughts”
