You buy a chair. That is a good. It has weight. It also exists in your home. You may also want to pay someone to fix it or hire a lawyer to claim ownership. It’s a service. Economists divide the entire economy into these two parts. Goods. Services.
The goods side is familiar. Agricultural. mining. Manufacturing industry. Construction. These create tangible objects that can be held. The service aspect is everything else. Here is the rest, which is sprawling remainder. Banking. Communications. Wholesale. retail. Professional services such as engineering, medicine and computer software development. Non-profit activity. Government services. defense. justice. It is all service.
Developed countries look like service-driven economies. In developing countries, most people still work in primary activities. they farm. They mine. They get their resources directly from the earth.
The transition to services has been steady and continuous throughout the 20th century. Look at the United States. In 1929, services accounted for just over half of Gross domestic product (GDP). By 1978, this share had risen to two thirds. By 1993, it accounted for more than three-quarters of the entire economy.
In the early 21st century, this trend intensified worldwide. Services currently account for more than three-fifths of global GDP. They employ more than a third of the world’s workforce.
Why is this happening? The simplest explanation is mechanization. Goods production is becoming more efficient all the time. Machines do the heavy lifting. With less labor, we can produce more tangible products than ever before. This efficiency creates a paradox. The goods sector is shrinking compared to the whole, even though it is producing more. Therefore, the service functions becomes relatively important. Distribution. Management. Finance. Sales. These human-centered tasks fill the gaps left by automation.
Growth in the service sector is also the result of a significant increase in government employment. As societies modernize as society modernizes. It administers justice. It protects borders. It regulates the market. All of these count as services.
These are not just abstract figures. It’s about where the work is. A place where value is created. The world is exchanging tangible things for intangible value. And this change is only accelerating.
