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”
In September 1999, NASA’s unmanned Mars climate probe “MCO” exploded in Mars’ orbit. Manufacturer Lockheed Martin set up the data unit as a “yard,” but NASA mistook it as a “meter.” The MCO entered the atmosphere of Mars 100 km below the original orbit and exploded in friction. Communication error had blown away $ 125 million. With this opportunity, NASA decided that the units used in space development were “meters”. A slip of the tongue in business doesn’t end just a mistake accidentally. It must undoubtedly damage the “cash flow”. - Joseph’s “just my thoughts”
