Did you grow up during the era of busing? I did. In principle I agree. In practice, not so much.

Then there is the problem of no schools in your neighborhood if you are poor. There are problems associated with that.

If you did bus how would that work? Not all the children from poorer neighborhoods will choose to go to the same school. Will a bus go 30 minutes in and 30 out to go get a kid? Then there is the burden on the child with potentially 2 hours on a bus.
