. What the heck is this GDP thingy? It is Thursday afternoon, just a few days before the holiday season starts in your region, and you decided to visit your uncle Chao who owns a local delivery company. While sitting in the living room watching the evening news with your uncle, you heard the news reporter stating the following with an optimistic tone: "According to recent studies, gross domestic product (GDP) is rising due to an increase in consumer spending. The increase in spending was due to an increase in consumer confidence because the job market has shown a positive increase in both employment and income." Immediately, your uncle Chao looked at you with some confusion on his face and asked: What the heck is GDP, and why does the news dude seem excited about its increase? Does this “good” change in this GDP thingy have any effect on my delivery business? How? Do I need to do something different to prepare for the rise in GDP? How?
