Black lives matter... but not as much as teachers unions?

New York's Mayor DeBlasio aims to close charter schools in NYC at the behest of his Teachers Union supporters (WSJ):

Good charters offer part of the answer. In New York, Eva Moskowitz’s Success Academy charter schools are arguably the best. Yet the mayor, his schools chancellor and the teachers union all apparently prefer maintaining the present inequality rather than allow Ms. Moskowitz to open more of her charters in poor minority neighborhoods.

The Success Academies are 58% black and about 27% Hispanic. Even so, these children regularly outscore their counterparts in wealthy suburban areas. So while each year the Success Academies prove that black kids can compete as equals with white kids so long as the bar is set high and teachers are held accountable, in the schools run by Mayor de Blasio the achievement gap between black and white has widened.
