“I can live well alone!” is not correct. If I live alone, I can survive to some extent, but ultimately, it is hard to survive, and “living well” is even more challenging. This is because the economic principle is established not by ‘alone’ but by ‘many people.’ If I live well, it means that someone has become poor because of me or is living well with me. The fact that through value exchange, or transaction, we can meet each other’s needs and store the surplus from that production is both true and real. Trading is not done in isolation. - 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”
