‘Equity in health’ means health for all, given our potentials and limitations. Its goal is to help each and every one of us achieve his/her optimal health by providing needed personal, social and environmental support. To promote health equity, both systematic and random variations in health status must be considered. There are numerous barriers to health equity, including the deep-rooted and dominant cultures of neoliberalism, nationalism, personal and political callousness, and technological imperative, which are responsible for widespread health inequities today. Proper conceptual frameworks are required to work towards health equity, including doughnut economics, planetary health, universal basic income, peaceful dispute resolution, an open-world strategy, and a global compassionate and cooperative culture. It is our moral obligation to be respectful and generous to others and work together cooperatively to refine, operationalize, and implement such conceptual frameworks to make the world a better place in support of global health equity.
