What underlying cause is primarily responsible for the shift from manufacturing-based economies to those driven by information and technology in postindustrial societies?

The main cause for the shift from manufacturing-based economies to those driven by information and technology in postindustrial societies is the advancement of technology. As new technologies developed, such as computers and the internet, they changed how businesses operate and how people communicate. This made it easier and faster to share information, which led to the growth of service industries like finance, healthcare, and education instead of traditional manufacturing. For example, instead of making physical products, many companies now focus on creating software or providing online services that can reach customers all over the world. This shift reflects how economies evolve to meet the changing needs and capabilities of society.
