"It is also important to note that natural birth control methods which the Catholic Church promotes, and which seem to be the root of this ridiculous claim, were not developed for the Roman Catholic Church but for use in Third World countries. The reason is simple: A condom costs the equivalent of a day's pay for the average Indian rural workman and two days' pay for a working woman. Interestingly, a study of 19,843 Indian women in the British Medical Journal in September 1993 showed conclusively that for these women in their culture and circumstances, natural birth control methods are more effective than are artificial methods in the west."
