The role of fathers/men

With the issue of having men feel that they should take more responsibility in the home, I wonder if our new culture of single working mothers and various fertility methods threaten what superiority men feel in the family order. Does that make sense? In other words, I guess I am saying the psychoanalytic approach behind why men overcompensate in the public sphere and subordinate woman, is to make up for their rather small part in the overall reproductive process. If you give women the public sphere equally and fully, this renders men as not having a dominant role either in the production of life nor in life itself.

My second question to pose comes from Oyewumi's piece where she states "According to Miriam Johnson, 'in the West the marriage relationship tends to be the core adult solidarity relationship..." (1094). This I believe is true. Why? And can we think of other adult relationships that hold significant value in our society and culture?
