Although the Fair Housing Act has done nothing to mandate the
active integration of American cities, Rothstein points out that it
does include useful provisions for more effectively combatting the politically convenient segregationist policies that continue to proliferate in city planning. This changes the grounds on which court cases about discriminatory housing policies can be fought: before, it was necessary to prove discriminatory
intent, but now it is sufficient to prove discriminatory
impacts—which is far easier. However, as always, merely stopping discrimination in the courts, after the fact, is only a way of preventing the problem from getting
worse than it already is—what is sorely missing is legislation that forces the government to
undo the
de jure segregation it has created.
