This study examines the extent and structural drivers of wealth inequality in South Korea and proposes policy measures to mitigate the widening asset gaps. The analysis reveals that asset disparities are shaped by complex interactions among life-course trajectories, asset composition, debt utilization, and the impact of intergenerational transfers through inheritance. From a life-cycle perspective, a coordinated policy approach is required that integrates social and tax policies, prioritizing support for low-and middle-wealth groups.
