The neo-material model may explain the link between poverty and disease better than other models. The neo-material model states that the infrastructure of the material world contributes to health inequalities just as much if not more than individual income. In the US, income inequality is associated with unemployment, health insurance, social welfare, work disability, and educational and medical expenditures. The political and economic processes that create income inequality influence individual resources and public resources such as schooling, health care, social welfare, and working conditions. A more equitable distribution of public and private resources have the greatest impact on health inequalities.
