Economics is important to study because virtually everything we do is about the economy. To find many jobs, and do many jobs you need to know about why and how the economy works. If you want to go into business you need to know about money and financing. If you are going to use credit to buy a house or a car, you need to know how the credit and banking system work. Economics are the rules that determine the price we pay for everything and the wages we earn when we work.
