Final answer:
The value of GDP in developed countries is now largely based on the service sector, encompassing healthcare, education, and financial services, indicating a shift from traditional manufacturing to knowledge and service-based economies.
Step-by-step explanation:
The makeup of the Gross Domestic Product (GDP) of developed countries has shifted significantly towards the service sector over the last decade. In developed economies, it's not the production of tangible goods like cars and computers that dominantly contribute to economic output, but rather a range of services. The service industry, which includes healthcare, education, and legal and financial services, now comprises more than 50 percent of the value of GDP in these countries.
These sectors reflect a modern economy where jobs are more likely to involve office-based activities such as analyzing data, digital communication, and professional interactions, rather than manufacturing physical items. The growth in the services sector correlates with a fundamental transformation in the types of work that drive economic activity in developed nations.
