Some economists would believe that is the modal action is to people keep the found wallet. I'm agnostic on it and I'm tempted to do the Northian, well, it depends how much money and it depends how hard it is to turn it back. That's a good place to predict as a total stranger. Most people will keep the wallet if it's really true that you're not going to be caught. It takes something that was noble and godly and turned into something. Todrian self-interested, right?
