“I can live well alone!” is not correct. If I live alone, I can survive to some extent, but ultimately, it is hard to survive, and “living well” is even more challenging. This is because the economic principle is established not by ‘alone’ but by ‘many people.’ If I live well, it means that someone has become poor because of me or is living well with me. The fact that through value exchange, or transaction, we can meet each other’s needs and store the surplus from that production is both true and real. Trading is not done in isolation. - Joseph’s “just my thoughts”
Compared to the era of a self-sufficient barter economy , everyone’s happiness is greater in the exchange economy , where each person divides their labor into what they do best and exchanges what they produce. This is because the division of labor is more efficient than self-sufficiency in productivity and can further reduce production costs. At this point, a means of exchange agreed upon by society is required, which is called money (currency). In other words, in the exchange economy, specialists who excel in one field are more advantageous for survival than ordinary people. An all-round player is more likely to face starvation. Therefore, a generalist is only advantageous for survival when they can organically integrate their diverse abilities in a specific field or situation, while also managing and restricting the scope of their activities and conditions. - Joseph’s “just my thoughts”
