"The severity of the housing shortage must be measured in terms of human distress. Children and adults crowded into small quarters cannot escape from the frictions and frustrations occasioned by too close and too constant proximity. The humiliations, squalor, ugliness and functional inadequacy of obsolete and temporary housing leave their permanent mark upon the occupants. It is for this reason that the ultimate territory on which a community must face its problems of housing shortage is in the slums and blighted areas. The inevitable cycle of housing history brings us back to this. "
