That reminds me of that joke:

Two economists are walking side-by-side.

One tells the other: I’ll give you $100 if you take a shit on the pavement.

He proceeds to shit on the pavement and grab the $100.

He then tells the other economist: I’ll give you $100 if you eat my shit.

The other does the deed and collects his $100.

After walking a few more blocks, one of them says: both of us left our dignity with that work back there and neither of us are any richer!

To which the other responds: no, but we grew our combined GDP to $200.

And they both walked away happy, patting each other on their backs.
