Economic Truths Revealed at a Drinking Party: From Troubling Net Values to the Challenges of Fertility in an “Online World”
Hello everyone, I’m your financial journalist and economist. Today, we’re going to dissect an article from “Tang Seng’s Random Thoughts.” On the surface, it seems like a casual conversation over a meal, but in reality, it’s a deep analysis of macroeconomics and behavioral economics disguised as a joke.
The author, Tang Er Seng, uses extremely accessible language, even with a touch of Beijing slang and gaming references, to connect three seemingly unrelated economic phenomena: the logic of asset price fluctuations, the valuation pitfalls in tech stocks, and the cost-benefit calculations behind birth rates.
Let’s break down the article into five key aspects to help you understand the economic principles behind them in plain language.

1. The Thermometer of Market Sentiment: Why Are Rebounds Getting Weaker?
The article’s opening mention of “troubling net values” describes a typical characteristic of the current capital market: a rebound with diminishing momentum, as if the market is losing its energy.
The author uses a vivid metaphor: a bouncy ball.
- Phenomenon: When you throw a ball on the ground and no new energy (new funds) is injected, it bounces lower each time.
- Economic Interpretation: The current stock market or fund net values are like that bouncy ball. The previous decline has consumed most of the energy, and without continuous inflow of new funds, the rebound will inevitably be weaker.
- Core Logic: To judge the market’s health, you can’t just look at whether it’s rising or falling; you need to see who is buying. If it’s just old investors trading with each other, the market’s potential is limited. Only when a large amount of new funds (such as retail investors, foreign capital, or government funds) continuously inject energy into the market can it sustain a strong rebound.
Lesson for the Average Investor: When market rebounds weaken, don’t rush to buy high. This is the market telling you: “We’re running out of fuel. Check how much fuel is left in the tank first.”

2. The “Faith” in Tech Stocks and Their Valuations: Who Is Swimming Naked?
This is the most interesting part of the article. Through a debate about tech stocks, the author reveals the biggest misunderstanding in investing: confusing industry prospects with stock prices.
- Viewpoint A (Optimists): They believe that tech industries (like AI and semiconductors) will thrive in the next few years, so they buy stocks regardless of the price, even with a 50x price-earnings ratio (PE), thinking profits will increase tenfold.
- Viewpoint B (Skeptics/Author): The industry is good, but the stocks are too expensive.
In-Depth Analysis:
1. High Prices Are the Real Problem: Many tech stocks are overvalued, as the market has already priced in perfect growth for the next 5-10 years. Any slowdown in growth or changes in competition could lead to significant price drops.
2. Risks of the Traditional Manufacturing Model: The author mocks those who expect tech companies to expand like traditional manufacturers. Tech companies’ advantages often lie in technology and patents, not scale. If these are disrupted, previous investments could be lost.
3. Misalignment of Confidence:
- Confidence in the Industry: People believe technology will improve and life will get better.
- Confidence in Stock Prices: They think prices will continue to rise.
Conclusion: You can be optimistic about the industry, but that doesn’t mean current tech stocks are good investments. “A good company” doesn’t necessarily mean a good stock, and a “good industry” doesn’t mean a good price.
Lesson for the Average Investor: Before buying tech stocks, ask yourself, “If this company’s profits only grow by 50% in the next five years, is the current price still worth it?” If the answer is no, you’re buying a bubble.

3. The Economic Essence of Birth Rates: A Shrewd Cost-Benefit Calculation
The second half of the article discusses birth rates. Instead of appealing to morality or emotion, the author uses rational assumptions and game theory to explain why people are having fewer children.
Core Logic: Having children is like creating new “accounts” in a game.
- In the Past (Early Stage): Costs were low; raising a child meant providing basic needs, and having more children meant more labor and opportunities for social mobility.
- Now (Late Stage/High Competition): Costs have skyrocketed; education, healthcare, and housing are extremely expensive, and children may end up in a worse situation than their parents.
- Alternative Options: It’s easier for adults to support themselves (e.g., with streaming or takeout), making it less profitable to have children.
In-Depth Analysis:
1. Diminishing Marginal Utility: In the past, more children increased overall family welfare; now, they reduce it due to resource allocation.
2. A Global Problem: This is not unique to China but a global challenge. Even countries with high birth rates are seeing declines, indicating a natural consequence of economic development.
3. Chinese Specificities: Education value has decreased, and the value of high degrees no longer guarantees high incomes. Automation has replaced many jobs.
Lesson for the Average Investor: Don’t blame young people for being “selfish” or “irresponsible.” In the current economic environment, not having children is often the rational choice for most families. Policy incentives must reduce costs (e.g., education and healthcare) and increase benefits (e.g., tax incentives, childcare).

4. Solution 1: Decoupling Sex and Reproduction—The Gamble Between Technology and Ethics
The author proposes a bold and forward-thinking idea: If marriage and sex are already decoupled, why not decouple reproduction as well?
- Current Challenges: Marriage is tied to complex issues like property division and social expectations, making it difficult for those who don’t want to marry to have children.
- Extreme Feminism: Some feminists use the right to reproduce as a bargaining tool, increasing the social cost of having children.
- Solutions: Artificial wombs or in vitro fertilization could allow single people to have children independently, eliminating the need for marriage.
- Benefits: It lowers the barriers to reproduction, allows for free choice of partners, and reduces power dynamics in marriages.
Lesson for the Average Investor: Future fertility policies and technology may redefine families and marriages. Technology is not only a driver of economic growth but also a shaper of social structures. Investing in space exploration and biomedicine is crucial for solving these issues.

5. Solution 2: Creating a “New Version”—Space Colonization and Population Reset
This is the most futuristic and profound part of the article. The author suggests that, given the current competitive landscape, birth rates are unlikely to improve significantly on Earth.
- Current Situation: Resources are limited, and competition is fierce. The wealthy and elite have already achieved success, while the rest face limited opportunities.
- New Possibilities: In space, wealth, status, and education would be reset, and physical, intellectual, and genetic advantages would become key.
- Reproductive Incentives: More people would mean more labor and genetic diversity, reversing the current negative trends.
- Historical parallels: Past migrations (e.g., to Southeast Asia or Northeast China) provided new opportunities. The same could apply in space.
Lesson for the Average Investor: Solving population issues may require creating new living spaces, not just monetary incentives. Investing in space exploration and biomedicine is key for human civilization’s future.

Summary
Although the article is written in a casual tone, it presents a clear and logical analysis:
1. Short-term Market: Be cautious due to weak market momentum and lack of new funds.
2. Mid-term Valuations: Tech stocks are attractive, but their prices may be inflated; be wary of bubbles.
3. Long-term Population: Declining birth rates are a result of economic rationality, not morality.
4. Long-term Solutions: Technology can change social structures (e.g., artificial wombs) or create new opportunities (e.g., space colonization).
In conclusion: In our current “online world,” we can’t rely on slogans to increase birth rates. The real solution lies in understanding valuation pitfalls and investing in technologies that can create new possibilities for humanity.
This article shows how financial and economic issues are often intertwined with broader social and technological trends.
