Final answer:
The quote suggests that every citizen plays a role in a nation's destiny, which in the context of today, can be related to the technology-driven economic growth. Individual and collective efforts in innovation contribute significantly to this growth, but also bring challenges that require careful management and responsibility from all citizens.
Step-by-step explanation:
A modern-day scenario for the quote 'The rise and fall of a nation rests with every one of its citizens' could be the influence of technology on economic growth. Technology is often cited as the most significant contributor to U.S. economic growth.
The efforts in research and development by citizens, whether as individual innovators or as part of firms and universities, drive the creation of new technologies that revolutionize the economy. However, with these advancements come a host of challenges such as investment willingness, positive externalities, and the role of government in research and development. Moreover, market failures in providing certain goods efficiently and the overuse of common resources are important issues. These factors collectively show how each citizen's contribution to technology can impact the nation's economic trajectory, embodying the shared responsibility in a country's rise or decline.
