When money interferes in a relationship, it changes the dynamic. Social norms and market rules come into conflict. For example, imagine a couple on a date, and when the man takes the woman home, he says, “I spent $100 on you today.” Suddenly, a romantic relationship shifts into a market transaction. Messages like “Next time, it’s your turn to pay” and “I did this for you today” appear. The benefits of social norms differ from those of market rules. Both are necessary, but the relationship is affected by when, how, and to whom they are applied. A person who fails to strike a balance between these two aspects risks damaging relationships and harming communities. - Joseph’s “just my thoughts”
You probably suspect that your decisions are reasonably based on your judgment. However, human decisions are made according to the rules and structures at that time. By changing the decision structure and regulations, humans make different decisions under the same conditions. If you make a mistake, you don't have to regret or blame yourself for making the wrong decision. But, if you fail to judge the regulations and structure of the decision, then you must reflect on the mistake. This is to prevent repeated mistakes. - Joseph’s “just my thoughts”
