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”
To obtain the information we seek, we invest time and effort in searching. During this process, there is a cost known as “information search cost.” If the search costs exceed the value of the information we wish to obtain, it is deemed inefficient; people generally aim to avoid inefficiency. For instance, if a billionaire spends considerable effort searching for a car for less than 90,000 USD, then the billionaire will just buy because it is inefficient. Cost-effectiveness in the economic world judgment is a crucial factor to get dominion world we’re living in. - Joseph’s “just my thoughts”
