Credit Rating and Required Rate of Return: Suppose you and Warren Buffett borrow money from a bank. The bank will assess your credit ratings differently. Maybe the bank could offer Warren Buffett a loan without interest since it can be advertised as a bank used by the renowned investor. However, it will likely charge you interest because you have a lower credit rating and less fame than Warren Buffett. The interest rate each borrower faces, based on their creditworthiness, is called the required rate of return for creditors. Under the same conditions, the cost of poverty is much higher for the poor than for the rich. Poverty inherently involves costs. - Joseph’s “just my thoughts”
In business, capital means business funds. A successful entrepreneur often says, "I started my business without any capital". It's partly true, but it's a lie. The entrepreneur just said that capital means only cash. However, all kinds of businesses need to be fundamentally business funds in any even not cash. The entrepreneur didn't count the founder's labor cost. No inputs, no outcomes. The uncounted labor costs are called "alternative costs" or "opportunity costs". This comes from comparative advantage. If the entrepreneur doesn't accept the uncounted labor cost as a debt, the entrepreneur is equivalent to losing the profit due to opportunity costs. Please always remember this. There is no free lunch in this world. - Joseph’s “just my thoughts”
