I asked my brother: What does it mean to make money?

He said: The boss gives you 200, and you do 200 worth of work—that's called exchanging a meal.
I said that's not right. The boss gives you 200, and you only do 50 worth of work—that's real earning.
He was stunned.
I told him, think about your company's supervisor—what do they do every day? Watching you guys not slack off. When you do well, he says it's because he's a good leader; when you mess up, he says he saw you couldn't handle it from the start.
My brother patted his thigh: Damn, I get it now.
The next day, he secretly transferred three of the company's clients to his personal account, working only two hours a day, and earning twice as much as before.
The supervisor came to talk to him: You can't do this; if the company finds out, they'll fire you.
He replied: Then you shouldn't be idle either. You're in charge of me, so I’ll give you 10%.
The supervisor's eyes lit up.
Now the two of them are partners—he's responsible for hiding things from above, and he's responsible for digging beneath. In half a year, they made over 400,000.
Yesterday, the company's audit uncovered it; the supervisor was the first to sell him out, claiming he was deceived.
My brother asked me what to do.
I said: Weren't you only doing 50 worth of work? Now you don't even need to do that.
A siren sounded from the phone.
