Nino Lo Bello, The Vatican Empire, “Behind the Walls III:”
Although most prices within the Vatican walls on items of food are concomitant with those of the neighboring country, and geared to Rome’s accelerated cost of living, general expenses are much lower. Vatican housekeepers, at least half of whom are males, do most of their grocery shopping on the grounds—but it’s necessary to go into Rome for such things as clothing, electrical appliances, and other durable goods. Sources in Rome supply the Vatican with its water and its electric power, while the Vatican’s so-called sanitation system empties into the Roman sewers. Without the help and good will of Italy, and especially of Rome, the non-self-sufficient Vatican would be unable to function efficiently.
