The United States and Great Britain had a perfect trade relationship for 150 years. Both sides were happy. Then, one day, we broke up this relationship for no reason. Then we fixed it by going back to where it was. Please don’t ask me why.
Here is how the art of a deal works: when something is functioning perfectly, you intentionally break it, fix it back to where it was, and emerge as a hero.
Also, the President of the United States called the chairman of the Federal Reserve a fool for not cutting rates to help him look better. Messing with the most powerful and politically independent organization in the world, which can do anything they want with the economy, is probably the art of a deal as well, I suppose.
