Jim and Steve are die-hard capitalists...
They go for a stroll together through a cow pasture, and Jim tells Steve that he will give him $20,000 to eat a pile of cow flop. Steve considers the suggestion, says what the heck, and eats a pile. Jim, laughing, gives him the money, and they continue on their merry way.
After a few minutes, Steve tells Jim that if he eats a pile of cow flop as well, he will give him $20,000. Jim considers and eats one too. Steve chuckles and gives Jim the money.
After another few minutes a concerned look of realization appears on Jim's face. He asks Steve, "Did we both just eat cow flop for no reason?"
Immediately, Steve replies confidently, "No way! We just created two jobs and $40,000 worth of GDP!"
