Why did the rancho los amigos asylum close down?

The Rancho Los Amigos National Rehabilitation Center is still operational today and provides care for individuals with physical disabilities. The term "asylum" may be outdated and referring to when mental health care institutions were more prevalent before advancements in community-based mental health care. Many mental health asylums closed down due to shifts towards community-based care and deinstitutionalization efforts to promote more humane and effective treatment for individuals with mental health conditions.
