These guys are part of a cause-less generation. They didn't grow up burning their draft cards or fighting the Nazis. They weren't part of the Civil Rights Movement, the Women's Movement, or any other movement. They were spoiled as kids and now they want to spoil themselves as adults. The old cliché was that a man would wake up one morning and realize that he wanted his youth back. The new version is that he never reached adulthood in the first place.
This type tends to be drawn to Type-A women who can bring home the bacon, fry it up in a pan, and never let him forget he's a man . . . but the writer wonders if part of what the male commitmentphobe is thinking is that this type of woman doesn't need him at all. (Hmmm. So it's her fault?)
I don't think many would argue for a return to old-school gender roles and the suffocation that went with them, but do you think there's a whole generation of young-ish men who don't know how to commit?
