Many global issues—such as climate change, inequality, and financial instability—derive from a deficiency in the moral foundations of capitalism. These collective action problems persist because current measures of prosperity, such as GDP, fail to capture the true well-being of people and the planet. A more holistic approach to measuring prosperity is needed, one that includes economic, social, and environmental domains. The economic domain focuses on sustaining life with dignity without harming others. The social domain emphasizes social solidarity and individual and collective agency. The environmental domain highlights the responsible use, protection, and regeneration of natural ecosystems. This new framework is guided by four key principles: universalizability—ensuring global relevance; simplicity—limiting the focus to key well-being components; regularity—tracking well-being as often as GDP; and national scope and duration—applying these measures widely and consistently over time.
