Britain and France won the war in part because they were able to assure the health and well-being of their population. Fair systems of rationing saw the living standard of elites fall, but the living standard for much of the population rose. For those who were not in the age group that went to war, life expectancy, at least in Britain, went up. Restrictions on the consumption of alcohol—the potency of beer was reduced by law, as were the hours when alcoholic beverages could be served—prolonged the lives of those accustomed to drink to excess. But it also meant more money left over to provide for their families. Even more important, the wartime prosperity resulting from the boom in factory jobs meant more money for children's clothes and shoes. Ironically, war bread provided more nourishment than the kind most Britons ate in normal circumstances.
