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”
Economic activity must accompany a counterparty. Since people couldn't live alone anyway, they exchanged whatever goods met their needs, and as a result, an "economic system" was created. The standard of exchange is called "value" and the numerical representation of it is called "price. "Value" and "price" certainly do not necessarily match, and one of the main reasons is "competition. In the end, value is exchanged for price. Values are offered at the pricing initially presented by others or at a provider's insistence that wants to earn profit at first. If only the offered price is recognized by others, the recognized price is accepted as its determined value. The price of one's wage agreed upon with another is the real price of one. All other evaluations and recognitions except the above are only self-justifications and excuses. - Joseph’s “just my thoughts”
