The "you have two cows" setup trains us to prefer economic systems that favor the upper classes. If I have two cows, of course I'm not going to want to let the government have any of my milk. But if it's actually that there's one person who has two hundred cows that they inherited from their grandparents, and I'm one of the 99 people who has no cows and works for the cow owner and I'm not paid enough to buy the milk that I spend all day milking, then I'm gonna have a different perspective.
