There's a fascinating article at the Los Angeles Times about a cultural shift amongst Iran's educated women. It seems that Western norms are taking hold amongst this group, leading to a declining marriage and birth rate in that country, as well as a higher divorce rate.
The article claims that the Iranian women are "liberated" but are held back by the men being too "traditional". But when you read through the interviews with these educated Iranian women a certain picture emerges. These women want things on their own terms. If the husband works too long hours, then they want a freedom to divorce him. But the husband has to accept it if she works long hours. They want a freedom to sleep around as they wish when young, but dislike it when they hit their 30s and want to marry and only meet men who want to sleep with them. An Iranian man in the comments also points out that they claim to want to be independent, but refuse to use their own earnings to contribute to household finances - they are suddenly traditional when it comes to men being the breadwinners.
I think it's evidence of just how easily a society can fall into a culture that is hostile to stable family formation.
