Medicare was primarily established to provide health insurance for elderly Americans. It was signed into law in 1965 by President Lyndon B. Johnson as an amendment to the Social Security Act. While it aimed to address the healthcare needs of a specific demographic (those aged 65 and older), the primary focus was on providing accessible and affordable health coverage for seniors, not explicitly as a response to societal mood regarding expanding legal rights for the poor and needy.
