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”
A newborn baby instinctively sucks its mother’s milk for survival, regardless of whether it learns this behavior. Chewing is also instinctual. The product that aligns with this chewing instinct is “gum.” While it involves chewing, it doesn’t equate to eating. Producing gum is a simple way to generate profit, given its common and low-cost nature. Therefore, the price of gum reflects the cost of chewing, differing from the prices of drinks and food. Since these items are consumed together, they exist in separate markets. The defining factor that separates these markets is “price.” Even if the products are similar, they operate within entirely different markets. - Joseph’s “just my thoughts”
