There is a concept that you may hear about often, which is called the middle class.

你可能經常聽到一個概念——中產階級。

Do you know the exact meaning of expression?
但你知道它的具體含義嗎？

It’s not just about being relatively wealthy.
不，并不只是“生活富裕”這么簡單。

The essential difference among the lower people, the middle class and the affluent class is not the difference of the amount of their wealth but the difference of the means they use to make money.
下層民眾、中產階級和富裕階層之間的區別，并不是絕對財富的區別，而是一種賺錢方式的區別。

The lower people use their dignity and health to make money.
下層民眾用尊嚴和健康賺錢。

The middle class use their skill and time to make money.
中產階層用技能和時間賺錢。

And the affluent class use their money to make money.
而富裕階層，他們用錢來賺錢。

Yes, in this way, they do get money by spending money.
對，他們的錢就是越花越多的。

It does sound absurd but in fact it has simple name which is investing.
這聽起來很玄乎，但它其實有個很樸實的名字，那就是“投資”。

The difference between the wealth of the affluent class and the middle class is the result of the difference between their lifestyles, not the reason.
富裕階層與中產階層之間的財富差距，是這種生活方式的結果，而不是原因。

Which kind of life do you want? Prepare yourself for it.
你想要那種生活？去為它準備好你自己吧。
