Mass-Care: The Campaign for Single Payer Health Care in Massachusetts, is a coalition of organizations and volunteer activists fighting for universal, public health care insurance in Massachusetts. Single-payer has proven in countries across the world to provide the most comprehensive coverage and the least costly delivery of health care to citizens and residents, guaranteeing individuals’ health as a human right. Health care reform in the United States has become a desperate plight, with rising costs, employers rolling back coverage of workers in both the union and non-union sectors, and the erosion of public funding for programs designed to offer care to some of the uninsured. However, the political process at both the national and state levels has proven incapable of making reforms that actually extend coverage or reduce costs. Mass-Care is committed to a grassroots organizing model that mobilizes communities to bring about real, comprehensive change that will extend health and dignity to all and bring the health care industry into check through a single-payer system.
