Segregation is wrong, but black students don’t need to share a classroom with white ones to learn

See Brown v. Board of Education: Right Result, Wrong Reason by Jason L. Riley. Excerpts:

"Warren’s claim that segregated schools produced inferior educational results was wrong when he wrote it in 1954. That year, an all-black high school within walking distance of the Supreme Court building sent a higher percentage of students to college than any white public high school in Washington. The same institution, Dunbar High, also had been known to outperform white high schools on standardized tests both locally and across the country. If the Supreme Court was correct in its assessment of racially separate learning facilities, how could Dunbar High School exist?

Nor were blacks the only ethnic group that had attended high-achieving segregated schools. “The most casual knowledge of history shows that all-Jewish, all-Chinese, or all-German schools have not been inherently inferior,” the scholar Thomas Sowell has noted. “Chinese and Japanese school children were at one time segregated both de facto and de jure in California, yet they outperformed white children—and largely still do.”"

"What we do know is that efforts since the Brown ruling to integrate public schools have done more to sustain academic achievement gaps than to narrow them. Charter schools, which concentrate in low-income minority neighborhoods to offer education alternatives, are resisted on grounds that they perpetuate racial segregation. That many charter students outperform their peers in traditional public schools is an afterthought."

"In some of the best public schools in the country, a majority of the students are black and Hispanic, which is also true of some of the worst public schools in the country. Clearly, the defining feature of a successful school isn’t its racial makeup"
