Paul, the roles that you describe are idealistic. Having two parents doesn't guarantee two adequate parents. The men who are suitable or outstanding parents (such as yourself) will be there and be the parent you describe.
There are still too many women who think that they're dating Paul Anka, and that the happy news will cause him to burst into a chorus of "Having My Baby". In the real world, sex is sex and too many men hit the road upon learning of the consequences or when they find out what a burden a child is, and they never really loved the mother anyway. 
As for health care for women and children, it's still the girls who birth and bring home the puppies. Her health is their health.
