White America has had another chance thrust before it, the chance provided by the violent death of a just man. The Kerner report, acknowledged and then quickly brushed aside a few weeks ago, is still there with its plethora of useful recommendations. The money being spent on the Vietnamese war proves that money is available to do just about anything the country wants to do or thinks it has to do. Here and there, business and the churches -- the two great conservative institutions in American society -- have begun to move. Both are beginning to see that the money must be spent; but they don't yet see how much, sharing with Congress and state legislatures the belief that they can buy Negro justice and equality with spare change.
