How Many Housewives does it Take?

This is a story about a man's tribe called "Saints", who live as a a totalitarian and fundamentalist society . These men's actions are cruel to these women, ranking them from the ability to be a wife, a housewife or a groundskeeper. Reasoning being is that recently the birthrate has plunged into a dark hole that seems to deepen as time goes on. So the men of this tribe came up with the idea of let women into their group for only one purpose. To repopulate and promote the growth and strength of their tribe.
