Five stories to help you understand economics.

**Story One: The Mango Scam**

Merchants create demand, drive up prices, induce herd behavior, and harvest retail investors.

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

But reality is not that simple.

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

Real estate has policy, credit, and demographic structure.

It's not something "cunning merchants" alone can control.

Key reminder.

The greatest value of this story is not teaching you how to fleece investors.

It's telling you: don't believe in "risk-free returns," don't chase "endless gains."

Greed is human nature's weakness, and manipulators bet on this.

**Story Two: Industrial Equipment Sales**

Hire 400 salespeople with 100,000 base salary, quota of 5 units per person.

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

This model sounds brutal, but has a prerequisite.

The product has real demand, real competitive pricing.

Otherwise 400 people can't sell anything, the boss goes broke first.

A reminder for those wanting to learn "leverage."

Don't just learn tactics, learn the product.

Sales is an amplifier, not an engine.

Weak product + more tactics = faster failure.

**Story Three: Planned Obsolescence**

Light bulbs last no more than 1000 hours, phone systems get laggier with updates.

This is called "covert strategy," sounds mystical, but it's just business.

But here's the thing.

Too good quality, company goes bankrupt.

Too poor quality, brand collapses.

Finding that balance point is real skill.

Advice for consumers.

Don't expect products that "last a lifetime."

Don't believe "more expensive = more durable" marketing.

Check reviews, compare specs, calculate residual value.

Rational consumption matters most.

**Story Four: Supermarket Prepayment Model**

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

1500 people pay up, the business collects 1.5 million in cash flow.

This model is everywhere now.

Hair salons, gyms, restaurants all use it.

But risks are huge.

First, merchant disappears.

You paid, the shop is gone.

High complaint costs, low recovery odds.

Second, consumption lockdown.

You think you scored a deal, actually got trapped.

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

Life-saving advice for those considering prepayment.

First, don't be greedy for massive discounts.

Charge 100, get 20 free is okay. Charge 1000, get 1000 free? Be alert.

The more outrageous the deal, the bigger the risk.

Second, choose chain big brands.

Small shops have low exit costs. Big brands have high breach costs.

Better to take less discount, get more security.

**Story Five: Money Circulation and GDP**

1000 yuan circulates 5 times, creates 5000 yuan GDP.

Two people trade feces for checks, create 100 million GDP.

The story exaggerates, but the logic holds.

Cash must circulate to create value.

Economics always has "speculation."

But don't let "encourage consumption" lead you.

Capitalists want you spending because they can't earn if you don't.

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

Spend what you should, save what you should.

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

**Final Truth**

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

Greed, fear, wanting deals, fearing loss.

These emotions are the underlying fuel of economic operation.

But stories are simplified, reality is complex.

Don't finish the stories thinking you understand economics now.

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

**Core Advice for Ordinary People**

Don't think "understanding economics" will make you rich.

First, do your current job well, master your skills solidly.

Economic cycles rise and fall, but ability is hard currency.
