Money is the most widely used medium of exchange worldwide, serving as a way to buy essential goods needed for life or to store wealth. Since the country guarantees the stability of fiat currency, it becomes possible to exchange ‘things for money’ instead of ‘things for goods,’ unless the country goes bankrupt. However, this amount of money cannot be increased indefinitely. When there is too much money in circulation, its value drops below the price of goods, causing those who hold wealth in money to lose that wealth. The key point is that money is limited in the market. Due to this limitation, money gains value. The government regulates this money supply through the ‘interest rate.’ Raising the interest rate reduces the money supply, while lowering it increases the supply. This helps control prices. Therefore, understanding the interest rate is crucial for managing and valuing wealth, making it essential to know the interest rate above all else in life. - Joseph’s “just my thoughts”
Architecture has developed in response to the epidemic. The city was designed to mitigate the risk of outbreaks. However, its high population density renders it susceptible to epidemics. A potential solution to this issue involves the construction of a water supply and sewage system, which safeguards individuals from waterborne infectious diseases (e.g., cholera) by effectively separating and burying water and sewage underground. Nonetheless, the advent of vaccines has facilitated the existence of megacities with populations exceeding 10 million people. Indeed, microorganisms predominantly populate the Earth. - Joseph’s “just my thoughts”
