My second uncle and my third uncle came home for the New Year and gave me an economics lesson.

At the New Year's Eve dinner, second uncle had a little drink, patted the table, and said to third uncle: If you dare to run around the village completely naked, I’ll give you fifty thousand.
Third uncle said fifty thousand isn’t enough, ten times that—one hundred thousand.
Second uncle said deal.
Third uncle put down his chopsticks and went out.
In below-freezing temperatures, barefoot, he ran a lap on the frozen dirt road, returning with purple lips from the cold.
Second uncle laughed so hard he pounded his thigh and took out his phone to transfer one hundred thousand.
The next day, both of them didn’t look right.
Second uncle felt more and more like he lost; he didn’t get anything from the hundred thousand.
Third uncle, though he earned the hundred thousand, was laughed at by everyone in the village, and the emoji meme in the relatives’ group chat was already made.
Third uncle couldn’t take it anymore and told second uncle: You run a lap too, I’ll return your hundred thousand.
Second uncle, distressed over that hundred thousand, didn’t hesitate and ran out naked.
After running, he canceled the transfer.
Logically, this balanced things out.
But the two sat on the kang and calculated for a long time, only to find that they hadn’t gained much, and their faces were gone.
While they were feeling down, my cousin, a PhD in economics, pushed the door open to pay New Year’s greetings, and after hearing this, he was so excited he couldn’t keep his glasses steady:
“Uncles, you haven’t lost anything.
You used your own bodies to create twenty thousand yuan of GDP for the entire village this Spring Festival!”
That night, my second aunt prepared a full table of dishes, but neither of them touched a single bite.
