There is a very interesting pattern in history: whenever a large system feels that money is not enough, the first thing they tend to manipulate is the quality of that coin. In the late Roman Empire, mints kept adding lead to silver coins. Although the face value remained the same, the real purchasing power melted away like ice and snow. Why did they do this? Because they discovered a top-level lending trick: borrowing from the future, using the labor of the next few decades to exchange for a fixed parameter in the present. You think you own assets, but in reality, you've just signed a long-term extraction agreement, locking your most valuable youth into this game of chance. You lose all flexibility. Open your eyes and see clearly whether those things being aggressively marketed—requiring you to overextend your life to exchange—are assets or lead coins. In such cycles, the dignity of cash flow far exceeds the illusion of book value. So, try to avoid long-term, high-pressure lock-ins, keep your assets liquid, and ensure that when you sense something is off, you can immediately convert what you have into tangible supplies, rather than a pile of immovable bricks.
