Final answer:
The Supreme Court has not been able to eliminate all de facto segregation since the 1950s; while de jure segregation ended with pivotal court decisions and legislation, cultural and social behaviors have perpetuated de facto segregation, especially in education and housing.
Step-by-step explanation:
The statement that since the 1950s, the Supreme Court has eliminated virtually all de facto segregation in the United States is False. While the Supreme Court and federal legislation such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965 effectively ended de jure segregation (segregation enforced by law), they were not able to entirely eliminate de facto segregation, which is enforced through societal norms and personal behaviors.
Post-Civil Rights era, phenomena like "White Flight" exacerbated de facto segregation, especially in urban areas, as many white families moved to suburbs.
This trend, along with other socioeconomic factors, has maintained segregation in many communities to this day, particularly in public school systems. Thus, while legal barriers to segregation were dismantled, the cultural and social practices of segregation continued to persist in many forms.
