# Five Stories to Understand Economics

**The First Story: The Mango Scam**

Merchants create demand, inflate prices, induce herding, and harvest retail investors.

Translation: This is a simplified version of stock market manipulators and real estate cycles.

But reality is more complex.

Stocks have regulation, information disclosure, and short-selling mechanisms.

Real estate has policy, credit, and demographic structure.

It's not something one "cunning merchant" can control alone.

Key Reminder:

The greatest value of this story isn't teaching you how to fleece retail investors.

It's telling you: don't believe in "guaranteed profits," don't chase "endless rallies."

Greed is human weakness, and manipulators are betting on exactly that.

**The Second Story: Hardware Equipment Sales**

Hire 400 salespeople, base salary 100k, quota 5 units.

End result: 30 people remain, 600 units sold, millions in profit.

This model sounds harsh, but has one prerequisite.

The product truly has demand, the price is truly competitive.

Otherwise, 400 people can't sell anything, and the boss loses money first.

A reminder for people wanting to learn "leverage."

Don't just learn tactics, learn the product.

Sales is an amplifier, not an engine.

Bad product, more tactics, faster failure.

**The Third Story: Planned Obsolescence**

Lightbulb lifespan capped at 1000 hours, phone systems lag more with each update.

This is called "yin-invading-yang trickery," sounds mystical, it's actually business strategy.

But here's the thing.

Too good quality, company goes bankrupt.

Too poor quality, brand collapses.

That sweet spot in the middle—that's real skill.

Advice for consumers:

Don't expect a "lifetime product."

Don't believe the "pricier means more durable" marketing.

Read reviews, compare specs, calculate residual value.

Rational consumption matters most.

**The Fourth Story: Supermarket Prepayment Model**

Charge 1000, get 1000 free, then 1000 rebate, lock users in for 2 years.

1500 people charge, recoup 1.5M in cash flow.

This model is common now.

Salons, gyms, restaurants all use it.

But risks are huge.

First: Merchant disappears.

You charged money, store vanishes.

Claim costs high, recovery rates low.

Second: Consumption lock-in.

You think you got a deal, actually you're trapped.

Don't want to go? Tough, the money's wasted anyway.

A life-saving tip for people considering prepayment.

First: Don't be greedy for huge discounts.

Charge 100 get 20, okay. Charge 1000 get 1000, stay alert.

The more outrageous the discount, the bigger the risk.

Second: Choose large chain brands.

Small shops have low switching costs, big brands have high breach costs.

Better to get less discount and more security.

**The Fifth Story: Currency Circulation and GDP**

1000 yuan circulates 5 times, creates 5000 yuan GDP.

Two people swap manure for checks, create 100M GDP.

The story's exaggerated, but the logic is sound.

Cash creates value only when circulating.

Speculation always exists in economics.

But don't be led by "encourage consumption" narratives.

Capitalists want you to spend because that's how they profit.

But your money is your sweat and blood, not their harvest.

Spend what you should, save what you should.

Don't be hijacked by "circulation creates value."

**Finally, the Truth**

These five stories are fundamentally "human nature + rules" games.

Greed, fear, wanting deals, fearing loss.

These emotions fuel the economic engine.

But stories are simplified, reality is complex.

Don't finish these stories thinking you understand economics.

People who truly understand economics don't teach you to get rich through stories.

**Core Advice for Ordinary People:**

Don't think "understanding economics" makes you rich.

First, do your current job well, solidify your skills.

Economic cycles have ups and downs, ability is hard currency.
