If you’re alone on an uninhabited island, you don’t need money; you only need resources and labor to process those resources for survival. In other words, there’s no need for an exchange-based economy. The exchange of goods led to the development of an economic system that dramatically increases efficiency and productivity. The monetary system was created because society consists of many people living together. To facilitate exchange, value had to be measured, and a price assigned to that value. The foundation of wealth is built on production and exchange. We all rely on others to survive. - Joseph’s “just my thoughts”
In the USA, even in one country, the time difference between the west and the east is 3 hours. People thought that time was a natural thing. But it is not. It's very political. The time that man lives in a unit of minutes is too short. However, since the invention of the steam locomotive, the appearance of faster vehicles made crazy changes to the concept of time. The shift in distance made people realize what time was. Sandford Fleming, an engineer and inventor, asked to unify the time difference caused by long-distance transportation, but people rejected his request. If the boarding time were not fixed, the railroad would be useless. The history of the 24-hour clock was made only about 140 years ago. Even with the invention of high technology, if nothing is consensus, nothing benefits. - Joseph's "just my thoughts"
