It’s true that busing didn’t really work very well. It was a clunky approach to a horrible problem of school inequality. It was an incredibly brave plan, particularly in the face of the extraordinary racism in Boston during the 1970s. I’m not sure how it could have really worked in a functional way though.
Meanwhile, for all our patting our own backs about racism not being as bad as it was forty years ago, school segregation and inequality remain intractable problems.
