Men feel their role is to look after women. They want to feel they count. Many women respond competitively by insisting they can look after themselves ... If women really feel men are redundant, they have to decide so. Either their lives are better with men in them or not. If she decides to include a man in her life, she needs to validate that man's contributions - and out loud.
The only thing I'd add, is that by the time women hit their 30s, they're often happy to accept a need for men. In my experience it's usually women in their 20s who are hell bent on proving their independence and autonomy.
