Public schools have always been meant to provide all children with the skills and knowledge to become successful participants in the economy. But currently, a second important purpose of public education has become more salient: to promote social cohesion in a diverse and fractured democracy. As ugly and naked racism in America is further unveiled, how can schools be a tool for combating racism and promoting unity? Ideas on a way forward can be found in the Supreme Court's landmark 1954 decision in Brown v. Board of Education. The court was explicit in describing the damage that school segregation inflicted on children of color. Less discussed, both in the court opinion and in public discourse, is the body of research that outlines the educational and moral damage that segregation inflicts on white children. This article argues why racial and socioeconomic school integration has proven to be one of the most powerful strategies known to educators to improve the lives of students and reduce national division.
