Welfare as a right has long been an objective of advocates for social and economic justice. During the 1960s, the right to welfare was championed by legal scholars as well as the activists who created the National Welfare Rights Organization (NWRO). With the demise of NWRO in 1975 and the subsequent ascendance of conservatism in social policy, notably the 1996 welfare reform act, momentum for welfare as a right flagged. Since the 1990s, a capability approach to well-being has been proposed, and various instruments have been constructed to evaluate the welfare of populations across nations as well as subnational jurisdictions. Variables such as income, health, education, employment, and satisfaction measures of well-being have effectively replaced the idea of welfare as a right. The transition from welfare as a right to well-being varying across populations provides more information social workers can use to advocate for marginalized populations.
