Public policy bearing the labels of elder rights and elder justice is scant and only recently appeared on the scene. The terms “elder rights” and “elder justice” have been largely appropriated by the field of elder abuse, which has applied them narrowly to policies and programs that address elder and dependent adult abuse and mistreatment. But “aging policy” in the United States is grounded in social justice principles and goals. This explains how Social Security, Medicare, Medicaid, Supplemental Security, the Older Americans Act, and the Elder Justice Act have advanced individual rights and social justice. It also explores how discrimination against older people has been addressed, explicitly, through measures like the Age Discrimination in Employment Act, and by policies that protect older people as members of other groups. This includes laws and regulations that protect people with disabilities, residents of institutions, consumers, crime victims, prison inmates, and others.
