1
I just spent the last two weeks reading a 700-page book by Thomas Sowell, a Stanford economist.
2
It's called Basic Economics.
3
The economy seems confusing and complicated, but it's not.
4
Most people never learn how it actually works,
5
so they keep getting fooled.
6
By the end of this video,
7
you will understand why taxing the rich hurts the poor people the most,
8
Why making rent cheaper creates housing shortages.
9
Why making food cheaper makes it disappear.
10
I know it all sounds backwards,
11
but once you see the proof, you can't unsee it.
12
So, let us start.
13
The year is 2008.
14
The state of Maryland has a problem.
15
They need money.
16
So, someone comes up with an idea.
17
Let's tax rich people more.
18
Maryland had about 8,000 millionaires.
19
They do the math and say,
20
if we raise their taxes,
21
we'll collect $106 million more every year.
22
Done!
23
Problem solved.
24
Everyone celebrates.
25
Here's what actually happened.
26
Year one, they collected the tax.
27
Everything is going to plan.
28
Year two, somebody counts the millionaires again.
29
There were only 6,000 left.
30
2,000 millionaires had just vanished.
31
They moved somewhere else.
32
Instead of gaining 106 million,
33
Maryland actually lost 257 million in total tax revenue.
34
Oregon tried the same thing,
35
raised taxes on high earners and lost billions over time.
36
And here's the lesson.
37
And I really want you to get this.
38
People respond to rewards, not intentions.
39
Maryland intended to raise money,
40
but what they actually did was reward millionaires for leaving.
41
So the millionaires left, and they took their businesses,
42
their restaurants, their companies with them.
43
The jobs disappeared.
44
Now, you can wish that people would just sit there and accept higher taxes,
45
but intentions don't matter.
46
Rewards do.
47
What this means for you,
48
in your business, your relationships, your life.
49
Don't ask what you want people to do.
50
Ask what you're rewarding them to do.
51
Number two, every choice has a cost.
52
Let's say you have $10.
53
You want a Starbucks, a burger, and a movie ticket.
54
Can you have all three?
55
No, 10 bucks is 10 bucks.
56
You get the Starbucks, you skip the burger.
57
You get the burger, forget the movie.
58
Every single choice means giving up something else.
59
That's a trade-off.
60
Economics is not about what you have,
61
it's about what you do with what you have.
62
And this isn't just with small things,
63
this is how the world works.
64
For example, Venezuela has massive oil reserves.
65
They should be rich, but they're broke.
66
Switzerland has nothing in the ground.
67
They should be poor, but they're one of the richest countries on Earth.
68
The same rule applies to you.
69
Every dollar you spend, every hour you work,
70
every person you hire, it can only be used once.
71
The real question is not, can I afford this?
72
It's, what am I giving up to get this?
73
For example, you buy a BMW for $50,000.
74
Beautiful car.
75
Leather seats.
76
You feel like you made it.
77
But here's what you didn't see.
78
If you bought a Toyota Corolla for $20,000 instead and invested the extra $30,000 in 10 years,
79
it could almost be worth $60,000.
80
In 30 years, you are looking at almost $250,000.
81
That BMW didn't cost you $50,000.
82
It cost you a quarter million.
83
That's the trade-off.
84
Every time you spend money,
85
you're not just spending money.
86
You're spending what that money could have become.
87
Same with your time.
88
Same with your energy.
89
Same with your attention.
90
Once you start seeing trade-offs, you can't unsee them.
91
And that's either the most terrifying thing you'll ever learn or the most powerful.
92
Number three, prices are messages.
93
There's this famous story.
94
Soviet leader Gorbachev visits Britain and asks Margaret Thatcher,
95
how do you make sure people get food?
96
She replies, I don't.
97
Prices do.
98
Think about that.
99
London has not grown enough food to feed itself for over a century.
100
Millions of people, three meals a day.
101
There is no minister of sandwiches.
102
No government office decides where the bread goes.
103
And yet every morning, fresh fish arrives from Norway,
104
beef from Argentina, coffee from Brazil.
105
Nobody is coordinating this.
106
Prices are.
107
Let me show you why no human could ever do what prices do.
108
Imagine you're in charge of all the pizza in your country.
109
Not one pizza shop.
110
All of it.
111
Your job is to make sure everyone who wants pizza gets it.
112
You would need to know how many people want pizza today versus tomorrow,
113
which cities need more, what toppings,
114
how much cheese to make,
115
which means deciding how much milk goes to cheese versus ice cream,
116
how many tomatoes to grow,
117
how many ovens to build.
118
And all of this changes every single day.
119
You cannot know all this.
120
No human can.
121
No computer can.
122
Too many variables changing too fast.
123
But this problem gets solved every single day.
124
Remote little towns get pizza.
125
Big cities get pizza.
126
Nobody is in charge.
127
Nobody is planning it.
128
Prices do it.
129
When pizza is scarce, prices go up.
130
suppliers rush to make more.
131
When there is too much,
132
prices drop, suppliers slow down.
133
Nobody sends these messages on purpose.
134
They just happen, based on how many people want something and how much of it exists.
135
The price isn't the enemy.
136
The price is the only one telling you the truth.
137
So the next time you see a price that makes you angry,
138
just pause for a second.
139
Ask yourself, What is this price trying to tell me?
140
Is something scarce?
141
Are too many people chasing too little supply?
142
The price isn't the problem.
143
It's the only honest signal you've got.
144
Number four, price controls never work.
145
New York City has thousands of abandoned apartments just sitting there, empty.
146
Meanwhile, homeless people sleep on the street right outside those buildings.
147
There are four times as many abandoned apartments as homeless people in New York.
148
Let me show you how this happens.
149
Imagine your school makes an announcement.
150
Tomorrow, free pizza at lunch.
151
Unlimited.
152
Take as much as you want.
153
At first, just the kids who normally buy lunch show up.
154
Small line, normal.
155
But word spreads fast.
156
Now everyone shows up.
157
Kids who usually bring lunch from home,
158
kids from other grades, everybody.
159
And everybody's grabbing extra slices, just in case.
160
20 minutes later, the pizza is gone.
161
The early kids hoarded everything.
162
The ones who came late got nothing.
163
This is what happens every single time you mess with prices.
164
Now go back to New York.
165
Rent was getting expensive.
166
People were struggling.
167
So politicians step in.
168
They make a rule.
169
Landlords can't charge more than a certain amount.
170
Rent control.
171
Problem solved, right?
172
Wrong.
173
At the lower price, suddenly everyone wants their own place.
174
The college student who is going to stay with his parents now gets his own apartment.
175
The widow who was thinking about moving in with the family keeps her three-bedroom to herself.
176
Remember the free pizza example?
177
the same thing happens here.
178
Everyone grabs extra and the people who actually need it get nothing.
179
But wait, it gets even worse.
180
If landlords can't raise rent, they stop fixing things.
181
They stop repairing roofs.
182
Buildings start to rot.
183
Eventually, some landlords just walk away entirely.
184
And that is how you get thousands of empty apartments in a city full of homeless people.
185
Price controls made them worthless to operate.
186
Same pattern with food.
187
Zimbabwe artificially kept prices low during the inflation crisis.
188
Stores emptied within hours.
189
Farmers just stopped bringing food to market because selling at the controlled price meant losing money,
190
so they didn't sell.
191
People starved while crops rotted on farms.
192
This is what happens when you set prices too low.
193
Now let me show you what happens when you set the prices too high.
194
India, early 2000s.
195
The government wanted to help farmers,
196
so they guaranteed a high price for wheat.
197
No matter what happens, farmers get paid well.
198
Sounds great, right?
199
Wrong again.
200
If the government guarantees a high price,
201
farmers grow more wheat to make a profit.
202
So that is what they did.
203
They produced way more wheat than anyone could need.
204
And the government had to buy it all.
205
11 million tons of wheat piled up in warehouses.
206
And then it rotted, while people in other parts of the country we're starving.
207
So here's the pattern.
208
Set the price too low,
209
shortage, people can't get it.
210
Set the price too high,
211
surplus, product rots while people starve.
212
Either way, you mess with the prices, you break the system.
213
And here's the cruel part.
214
Price controls are supposed to help the poor.
215
But when the thing disappears, rich people find workarounds.
216
They bribe someone.
217
They know someone.
218
Poor people suffer the most.
219
The solution becomes the problem.
220
What this means for you,
221
when a politician promises to make something affordable by controlling the price,
222
ask one simple question.
223
What happens to the supply?
224
Number five, profits and losses are directions.
225
Picture a school lunch table.
226
You notice kids go crazy for fruit snacks.
227
So you start bringing extra packs and trading them for stuff you want.
228
It works.
229
You're making a profit.
230
The profit tells you something.
231
Keep going.
232
Bring more fruit snacks.
233
People want them.
234
Now imagine you try the same thing with raisins.
235
Nobody wants them.
236
You cannot give them away.
237
That is a loss.
238
You wasted your allowance on something nobody wanted.
239
That loss also tells you something.
240
Stop.
241
Try something else.
242
Profits say, yes, do more of this.
243
Losses say, no, stop doing this.
244
Simple, but here is what most people miss.
245
Losses are just as valuable as profits.
246
Maybe more.
247
When a company keeps losing money and shuts down,
248
it sounds sad, but it's good for everyone else.
249
That company was using engineers,
250
steel, electricity, trucks, all to make something people didn't want.
251
When it dies, those engineers go work somewhere useful.
252
That steel gets melted into something people actually need.
253
But here is where governments break the system.
254
They say, this company is too big to fail.
255
We will give them money to keep going.
256
Now the signal is broken.
257
The company was supposed to stop.
258
Instead, it keeps wasting resources on stuff nobody wants, funded by your taxes.
259
It's like paying the raisin kid to keep bringing raisins forever,
260
and everyone else just has to deal with it.
261
Profits are not the enemy.
262
Losses are not the enemy.
263
They are the honest feedback the economy has.
264
What this means for you.
265
Look at your life right now.
266
The things making you money,
267
making you happy, moving you forward.
268
Do more of that and kill that side project bleeding cash for three years.
269
Don't feel bad.
270
That's not failure.
271
That's the market telling you the truth.
272
The moment you kill it,
273
you get your time and energy back.
274
Now you can put all of that into something that actually works.
275
Number six, your wage is a price too.
276
Why do some jobs pay more than others?
277
Construction workers lift heavy stuff in the sun all day.
278
They don't make that much.
279
Nurses keep people alive.
280
They're not millionaires.
281
So what's the real answer?
282
You get paid based on how much value you create.
283
That's it.
284
Let me show you.
285
You have a lemonade stand.
286
You hire your friend Maria to help.
287
How much can you pay her?
288
Well, it depends on how much extra lemonade she helps you sell.
289
Maria's fast.
290
She's friendly.
291
With her there, you sell 10 more cups at $1 each.
292
That's $10 of extra value in your pocket you can pay her up to $10 and still break even.
293
Now, imagine you hire your other friend Jake.
294
Jake's slow.
295
He's on his phone, spills the lemonade.
296
With him there, you only sell two extra cups.
297
That's $2 of value.
298
Pay him more than that and you're losing money every hour he's standing there.
299
This isn't mean, it's math.
300
Now, here's where people get fooled.
301
Someone says, workers deserve a living wage.
302
Raise the minimum to $15.
303
Sounds nice.
304
But what if a worker only creates $10 of value per hour?
305
You're now forced to pay $15 for $10 worth of work.
306
You lose $5 every single hour.
307
No business survives that.
308
So what does the business owner do?
309
He doesn't hire that person.
310
He buys a self-checkout machine instead.
311
He cuts hours.
312
He closes the shop.
313
So here is what this lesson means.
314
Your boss isn't paying for your time.
315
He's paying for your results.
316
More valuable results?
317
More money.
318
Want to earn more?
319
Create more value.
320
Learn the skill nobody else wants to learn.
321
Number seven.
322
Trade makes everyone richer.
323
You've got a sandwich.
324
Your friend has pizza.
325
You each kind of want what the other person has.
326
So, you trade halves.
327
Did the total amount of food change?
328
No. But are you both happier?
329
Yes.
330
That's trade.
331
It creates value without creating more stuff.
332
Nobody lost.
333
You didn't beat your friend, she didn't beat you.
334
Both of you won.
335
Now, here's where adults completely mess this up.
336
Politicians talk about trade between countries like it's a war.
337
We're losing to China.
338
They're stealing our jobs.
339
We need to win.
340
But trade isn't a game with winners and losers.
341
If it were, why would both sides keep doing it,
342
year after year, century after century?
343
One country buys stuff from another because it's cheaper than making it themselves.
344
The other country sells because they get paid well.
345
Both countries end up with more stuff than if they tried to make everything on their own.
346
Both win.
347
Now, here's the part that blows people's minds.
348
Even if one country is better at making everything,
349
trade still helps both countries.
350
Think about it this way.
351
Imagine you're a lawyer who charges $300 an hour.
352
You're also pretty good at cleaning.
353
Should you clean your own office?
354
No. Hire a cleaner for $20 an hour.
355
Use that hour to do legal work instead.
356
You make 300, pay 20, and you're way ahead.
357
Countries work the exact same way.
358
One country might make both cars and shirts better than another country,
359
but if their advantage in cars is huge and their advantage in shirts is small,
360
it makes sense to focus on cars and trade for shirts.
361
Both countries end up with more cars and more shirts than if they each tried to make everything alone.
362
That's why economists across every political view have supported free trade for 200 years.
363
Trade isn't war, it's cooperation.
364
Both sides win.
365
Now, what this means for you.
366
Think about last week.
367
How many hours did you spend on stuff you're bad at and hate doing?
368
Emails, spreadsheets, admin work.
369
Imagine you paid someone 50 bucks to do all that,
370
and you spent those hours on the thing only you can do.
371
That's the trade.
372
This whole video comes down to one thing.
373
Trade-offs.
374
Every hour spent on your weakness is an hour stolen from your strength.
375
You don't win by fixing what's broken.
376
You win by doubling down on what's working.
377
That's economics.
378
That's life.
379
I want to end it by saying this.
380
Understanding economics won't make you rich,
381
but it will make you impossible to fool.
382
You just traded less than 20 minutes of your life to watch this video.
383
I hope it was worth it.
