"However, we still give up the essential things in our life and choose the dispensable diamonds. Is there a problem in our value system?"

Hearing the speech, the students were stunned.

Something wrong with the value system?

Oh, it's the most important and indispensable thing in life, but why don't they choose diamonds instead??

"In fact, you can get what you want, that is to say, this kind of thing is sufficient and not scarce, so we gave up the essential things and chose diamonds. Diamonds are scarce, while economics studies scarcity!"

"Scarcity is common in both society and individuals. Economics will come into being because of scarcity. When we study economics, we want to study and analyze this scarcity to maximize our own interests. This is the purpose of economics!"

At this point, everyone suddenly realized and opened up.

"Oh, I see!"

"My God, Xi hall is so easy to understand!"

"Yes, yes, to tell you the truth, I didn't understand a lot of theories just now!"

"God, economics is so useful? You can make a lot of money if you learn it, right?"

"Hahaha, what you said is reasonable. Isn't money our most scarce thing!"

"Yes, yes, I'm short of money, very short, very short!"

In a few words, the students were impressed by the perfect exposition of economics and what it studies.

Sun Weishu on one side was stunned and almost forgot to speak.

No, it's not forgetting, it's not knowing what to say.

It seems that there is nothing he needs to add!

I also want to hate Xia Xi. Don't hate me now. What they say is perfect, okay!

However, let him say praise, god horse, he doesn't want to say at all!

Because, how much can a student understand??

The only person he can praise is everyone in economics!! Or world-class economists, others, are not qualified!!

"Well, sit down!"

Sun Weishu held back a word for a long time. He went back bitterly and continued his lecture.

Just looking at Xia Xi again, the teacher snorted and bowed his head immediately.

"Hey, the teacher didn't say anything!"

"That proves that what I said in Xi hall is not bad?"

"Absolutely, at least it's much stronger than what residual value!"

Ann Xue frowned and lowered her head deeply.

She feels that the whole class seems to be targeting her now!!

Just said a surplus value. What's the matter??

What's her answer to the course she hasn't learned??

Damn Xiaxi, you're in the limelight again!!

Ann Xue became more and more angry, and then began to study hard.

Anyway, she is the monitor, and her grades must not be left behind!

At least get into the top three of the class!

An Xue began to work hard.

Sun Weishu didn't ask any questions until class was over.

College classes are relatively easy. There are not classes every day. Xia Xi has no classes tomorrow. She decided to go to Su's.

After school at night, she still didn't see Zhan Yu. Xia Xi rubbed her curly hair and went home alone.

The room was dark and Pine Valley didn't seem to be at home.

Isn't Zhan Yu at home?

Where did he go today? I didn't go to class.

"Zhan Yu, are you there?"

Xia Xi knocked on the door of the room. It was very quiet and there was no sound.

Aren't you here?

Xia Xi was stunned. Where did she go??
