A group of academics has outlined a framework for delivering high living standards to 99% of the global population while staying within planetary boundaries. The plan, detailed in research from the World Inequality Lab, proposes transforming economic and social systems to achieve what researchers call "an equal and habitable world."
The model envisions 90% of humanity doubling their income while working half current hours. The bottom half of the global population would see wealth share rise substantially from current levels, addressing the extreme inequality that concentrates resources among a tiny fraction of people. Researchers frame this not as deprivation for the wealthy but as systemic restructuring that benefits nearly everyone.
The academics acknowledge the proposal requires radical change. Current economic models treat planetary limits as optional constraints rather than hard boundaries. The plan demands shifting how societies organize production, consumption, and work itself. Key elements include reducing working hours across developed nations, redistributing wealth through progressive taxation and policy reform, and decoupling economic wellbeing from resource extraction and emissions.
The research confronts a persistent objection to climate action. Critics claim environmental constraints force impossible choices between living standards and ecological stability. This work argues the opposite. Wellbeing depends not on endless consumption but on security, community, health, and time. Most high-income nations already exceed the consumption levels needed for flourishing. Redistribution toward currently poor populations combined with efficiency gains in wealthy regions creates space for both equity and sustainability.
The framework requires political will more than technological breakthrough. Renewable energy, efficient transport, and sustainable agriculture exist. What lacks implementation at scale is the economic restructuring to deploy them fairly. Researchers point to specific policy levers: shorter work weeks, universal basic services, progressive wealth taxation, and investment in care work and public goods rather than private consumption.
The World Inequality Lab's analysis presents quantified pathways, not abstract ideals. It demonstrates that meeting basic needs for all while reducing
