None of this is true. Pretense engenders problems. As anyone knows who has dated childless women in their thirties, children are painfully important to them. For women the conflict between career and children is clear, distressing, and fundamental. For men, it isn't.
Security is more important to women than to men, and women have lost a lot of it.
Universal divorce leaves them at 35 trying simultaneously to work and raise kids, without help. It's just awfully hard. But it also isn't what they expected. Biologically women want men to protect and care for them. The new order isn't easy.
