As populations age and longevity increases, society continues to measure productivity, wealth, and human capital while overlooking one of its most valuable assets: wisdom. This article introduces the Wisdom Economy Framework, exploring how accumulated wisdom, tacit knowledge, mentorship capacity, generativity, and intergenerational learning contribute to societal resilience, continuity, and adaptive capacity. Drawing on insights from the United Nations, World Health Organization, World Bank, OECD, and leading scholars, it challenges traditional ageing narratives and proposes a new lens for understanding the hidden value embedded within aging populations.
