What do you think of the story "Castles in the Sky"?

Once upon a time there was a rich man who was stupid and ignorant. Once, he went to another rich man's home and saw a three-story building. The building was tall, large, magnificent, spacious and bright. He was very envious and thought to himself: "My money is not less than his, why didn't I think of it before?" How about building a building like this?" He immediately called the carpenter and asked, "Can you build a beautiful building like that house?" The carpenter replied, "I built that building." Said: "Then you build me a building like that now." So the carpenter began to measure the foundation, lay bricks, and build the building. The rich man saw the carpenter stacking bricks and was confused. He didn't know what was going on, so he asked the carpenter: "What are you planning to build?" The carpenter replied: "Build a three-story building!" The rich man added: "I Instead of building the second floor below, you build the top floor first." The carpenter replied, "No such thing! How can you build a second floor instead of the bottom floor? How about building a third floor?" The stupid rich man said stubbornly: "I just don't want the second floor below, you must build the top floor for me!" When other people heard this, they all Laugh at him.
