As recent projections warn that we’re off-track to reduce inequality for the 2030 deadline of the Sustainable Development Goals, the pressing need for equitable tax systems takes center stage at the 28th WIDER Annual Lecture on 4 September 2024. Esteemed economist Gabriel Zucman examines how disparities of current tax structures guarantee this inequality is persistent due to advantages enjoyed by the ultra-wealthy.
