In today's economy, many individuals rely on a variety of professionals for services ranging from healthcare to education and legal advice. As economic development progresses, the employment landscape shifts from primary industries to a focus on tertiary activities, where skilled service providers become pivotal. Tertiary activities include essential sectors like health, education, and communication, facilitating both production and exchange. The distinction between tertiary and secondary activities is highlighted, focusing on how services depend more on unique expertise and less on manufacturing processes. Trade, transport, and communication are cardinal aspects of these services, fostering a vibrant economy. The emergence of markets, both urban and rural, plays a significant role in supplying community needs, indicating that skilled roles in the service industry are crucial for economic growth.
