I think that's a quintessentially American fable. Most people will never achieve great success, but they can experience the thrill of imagining opportunity, and even if they know it's illusory, that moment of faith and effort before failure is the heroic action.
People will do stupid things like bet their life savings on a game or a bad idea, but they feel heroic for having tried regardless, knowing that if enough people keep trying, someone is going to succeed, and they get to experience that success vicariously in some small amount because they tried just as hard as the one who succeeded, experienced the same struggle, and somebody made it, even if it was never going to be them.
