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”
There are two types of businesses in this world when approached through the value of time and divided by the kinds of business: a business that requires discounting future value and a business that needs a surcharge. The bundle discount is a “future value discount business,” while the loan business is a “future value premium business.” Currently, it is unnecessary, but a bundle of sales is a business that offers customers incentives called “discounts” when they buy what they want in advance. The principal is not returned now in the loan business but must be returned in the future, providing the present incentive as a “delay repayment” in advance. Future discounts and surcharges can exist simultaneously in a business or a product; some enterprises will be ruined by mixing them if they change positions. - Joseph’s “just my thoughts”
