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”
History professor Yuval Noah Harari said, "The most distinguishing feature between humans and other animals is the ability to believe not exist imagination." If you eat a banana exchanged with a bill from the chimpanzee, then the chimpanzee must be angry with you. The bill is just a thing to believe non-existent imagination each other in the human world, it's never important and meaningful for the chimpanzee. Unless the belief is to exchange the value, the money is just paper. This belief makes our social community. - Joseph's "just my thoughts"
