I think it was a policy that came from a good place, wanting to promote integration and improving education outcomes for black people. But, I think it caused more harm than good. It was practically difficult for people to have their kids bused a long distance away. Also in some cases, it just lead to more rapid white flight and reorganization of white communities away from cities.
More broadly, I think the theory was pretty flawed. Going to a majority white high school doesn't solve the problems of poverty and racism which hold black kids back. The big difference in achievement between a school in Scarsdale and a school in Bed-Stuy, Brooklyn isn't the school itself. It's not the teachers, or building, or textbooks. It's the parents and students. Busing will never fix or even address that.
that and they focused on high schools rather than you know, actual kids. of course by that age you're much more likely to have fights break out and fixed racial attitudes
