Elon Musk’s favorite economist joke

Two economists go hiking through the woods.
They find a bunch of shit

One economist tells the other:
“i’ll pay you 100 dollars if you eat it”

The economist eats the shit and gets 100 dollars

They keep going

Then they find another pile of shit

The other economist says:
“Now I’ll pay you 100 dollars if you eat this pile of shit”

He pays the other economist, and the other eats it

Then they say:
“Wait. We both just ate a pile of shit, and we don’t have any more money. We just gave each other 100 dollars, and we both ate a pile of shit. There’s no point to this.”

And the second one replies:
“No, no. Look at it from an economics perspective. We’ve just added 200 dollars to the economy”
