Some of these quantities refer directly to a point of time. That is true of "capital value" as also of such quantities as demand and supply prices. Other terms – as e.g. "income", "revenue", "return", "expenses", "savings", "investments" – imply, however, a time period for which they are reckoned. But in order to be unambiguous they must also refer to a point of time at which they are calculated.

Of all the calamities that have struck the rural Negro people in the South in recent decades—soil erosion, the infiltration of white tenants into plantation areas, the ravages of the boll weevil, the southwestern shift in cotton cultivation—none has had such grave consequences, or threatens to have such lasting effect, as the combination of world agricultural trends and federal agricultural policies initiated during the thirties.

In this sense the Negro problem is not only America's greatest failure but also America's incomparably great opportunity for the future. If America should follow its own deepest convictions, its well-being at home would be increased directly. At the same time America's prestige and power abroad would rise immensely.
