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”

What a person can do (possible) or cannot do (impossible) is referred to as that person’s CAPABILITY. Having a lot of CAPABILITY means that someone possesses many skills. Such individuals become generalists rather than specialists. A specialist is an expert in one field, possessing a prominent ABILITY, which gives them greater competitiveness in that area compared to others, while a generalist is often suited for roles like managers or investors who synthesize and evaluate information comprehensively. Additionally, a generalist can also become a type of specialist, depending on the choices made. - Joseph’s “just my thoughts”
