商品 or Inventory

In reality, price isn't determined by cost—it's determined by demand. A bottle of water is worthless by a river, but in the desert, it can be worth more than gold.

The mindset that "I put in the cost, so I deserve a return" is flawed. Returns are driven by demand, not cost. You can work hard and get nothing, or do nothing and still gain everything.

Investing is buying a monopoly.

What investors want is simple: a strong return on investment. You need to generate higher profits through your monopoly and pass those gains back to investors. If you don't, they'll simply walk away.

With domestic monopolies, investors are willing to put money in during the fundraising and market-expansion phase—when high profits are needed to sustain construction and rollout, like in oil. But once that phase is complete, they pull out. They understand that once you've achieved full coverage and infrastructure, you won't be rewarding shareholders; you'll be serving consumers (ensuring public welfare). As investors, they take their profits and leave.
