We don’t care about money deposited in the bank. If we ask the bank for money, I believe they will certainly return my funds. However, as shown by Lehman Brothers ’ bankruptcy during the 2008 financial crisis, banks cannot guarantee 100% of depositors’ money. In South Korea, according to the Depositor Protection Act, only 100 million won (about USD 71,000) is protected, including principal and interest per person. Anything beyond that is actually at risk. In other words, money deposited in the bank is vulnerable to losing the principal. Investing means willingly accepting the risk of losing the principal while seeking profit. Whether we like it or not, we are always investing in our daily lives. Just because a risk doesn’t materialize doesn’t mean it’s gone. - 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”
