In principle the war effort is always so planned as to eat up any surplus that might exist after meeting the bare needs of the population. In practice the needs of the population are always underestimated, with the result that there is a chronic shortage of half the necessities of life; but this is looked on as an advantage. It is deliberate policy to keep even the favoured groups somewhere near the brink of hardship, because a general state of scarcity increases the importance of small privileges and thus magnifies the distinction between one group and another.... And at the same time the consciousness of being at war, and therefore in danger, makes the handing-over of all power to a small caste seem the natural, unavoidable condition of survival.
