"... young heterosexual men such as Calvin seem to be avoiding that specific trap [namely, commitment]. As a result, many women in their 40s are sad and single without children or with fatherless children. In the 1970s, 1 in 10 women passed childbearing years without having a child. Today it's 1 in 5."
I see it differently. I see these women not as reacting to men who aren't interested in commitment, but as being influenced by feminism. Feminism freed them from the strong expectation that they needed to get married and have a child. Instead, they could have a career. Relationships and children were considered optional. Men really have nothing to do with it. It's all about feminism.
