Sally Kohn: The theory that you can move people around is premised on missing the role of segregation in mid-century American capitalism. And conveniently for new Democrats, this wasn't blaming the increasingly neoliberalized American capitalism. She says there was widespread agreement that just eliminating them without doing anything else would serve people and communities well.Kohn: It turns out to be a rather simplistic view of the world that suggests that all the forms of discrimination that produced segregation in the first place would somehow disappear if we could just rearrange people in space.
