Let's start with a joke: There were two economists walking down the street, discussing economic issues. Economist A saw a pile of dog poop and thoughtfully said to Economist B, "If you eat this pile of poop, I'll give you 1 million dollars." Economist B hesitated for a moment but couldn't resist the temptation, so he ate the pile of poop. Of course, as a condition, Economist A gave him 1 million dollars. After a while, Economist B also saw a pile of dog poop, so he said to Economist A, "If you eat this pile of poop, I'll also give you 1 million dollars." Economist A hesitated for a moment but couldn't resist the temptation either, so he ate the pile of poop. Of course, as a condition, Economist B returned the 1 million dollars he received from Economist A.
