Why could the difference between a 2.5 percent and a 3 percent annual growth rate be of great significance over several decades?

The difference between a 2.5 percent and a 3 percent annual growth rate can lead to substantial differences in economic outcomes over several decades due to the effects of compounding. Even a small percentage increase compounds over time, resulting in significantly higher levels of income, investment, and overall wealth. For instance, a 3 percent growth rate could double an economy's size in about 24 years, while a 2.5 percent rate would take about 28 years to achieve the same result. This disparity can affect living standards, funding for public services, and overall societal progress.
