"Milliken was perhaps the greatest missed opportunity of that period," said Myron Orfield, professor of law at the University of Minnesota. "Had that gone the other way, it would have opened the door to fixing nearly all of Detroit's current problems." John Mogk, a professor of law and an expert in urban planning at Wayne State University in Detroit, says, "Everybody thinks that it was the riots [in 1967] that caused the white families to leave. Some people were leaving at that time but, really, it was after Milliken that you saw mass flight to the suburbs. If the case had gone the other way, it is likely that Detroit would not have experienced the steep decline in its tax base that has occurred since then."
