What is the real moral of this story about economic GDP?

If the phenomenon in this story does happen in reality, it can only explain one problem, that is, GDP has indeed increased. . . Because the field of GDP does cover the added value of GDP created by the service industry, but GDP is a measure of economics, and the research premise of economics is based on the premise of rational people, so this joke is ridiculous. . . If you must ask who the irony is, I will tell you that the irony is those economists. In fact, the existing figures for calculating the national economic situation are not just a series of GDP data, which are closer to the actual economic growth than other measurement methods, so economists have adopted this data as the current reference standard. If you can come up with some more accurate data, you may be able to replace this stool in the future.
