Final answer:
The claim that there are no health differences among social classes in the US since the social programs of the 1960s is false. Health disparities have persisted and in some cases widened due to economic changes and uneven growth distribution affecting health outcomes.
Step-by-step explanation:
Despite the inception of social programs during the War on Poverty, health disparities among different social classes still exist in the US. The Great Society programs implemented under President Lyndon B. Johnson, such as Medicare, Medicaid, and the food stamp program, were substantial efforts taken to address the needs of lower-income Americans and did expand the federal government's role in providing a social safety net.
Nevertheless, disparities in access to healthcare and health outcomes have persisted, and in some cases, have widened since the 1960s. Issues like the growing income gap, the economic shifts away from manufacturing, changes in tax structures under supply-side economics, and the effects of the Great Recession have all contributed to the continued health differences across social strata. These structural changes have led to a situation where the economic growth of the country has not been evenly distributed, and this uneven distribution has had implications for health outcomes.
