Urban busing raised as many problems as it solved. It helped to drive much of the white working class to vote Republican. It helped to destroy a lot of the goodwill that had once existed between Jews and the black community. The ugliness of the white opposition in Boston rivaled anything that happened in the deep South.

I think many liberals now see busing as a mistaken policy; one which seemed to be a simple, and relatively cheap, solution to an intractable social problem. A comprehensive solution would have been much more difficult, much slower, and a lot more expensive. Real solutions usually are.
(I do like the references to "bussing" — it means "kissing".)
