They may drive Chevys, live in apartments, have no cell phones, and not eat out several times a week. But they realize that their children really don't care where they live, or what new car they ride in. Sacrifices are made out of selfless love and family commitment. Home-cooked meals, budgets, and creative family fun are realistic options for those who are willing and determined. Many families are doing this today and succeeding in a supposedly impossible one-income situation.
Many books are available on how to do it.
I am not sexist in thinking that women should be at home to raise their children. The important thing is that either the father or the mother needs to be there, full time. Society cannot continue to cheapen this responsibility to the level of children as playthings or pets. Even in the animal kingdom, disregarding parental instinct is unheard of. My mom would drive us to school in the morning, pick us up and make lunch at home, take us back to school, and pick us up at the end of the day.
