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”
A big supermarket can do business in the suburbs because of wheels. If someone asked me what is one of the greatest inventions in human history that civilization has ever developed, I would say "wheels." The automobile is also a wheel. Shopping carts are also wheels. Without wheels, how many people would go far and carry heavy loads? Mass distribution is possible because of wheels. To do bulk sales, you have to have a lot of inventory. That means you need a lot of storage space. It also means you need cheap real estate. The trivial circle, the wheel, is the key to solving all these constraints in one shot. - Joseph’s “just my thoughts”
