I agree with Rod Liddle, even though I haven't read the article fully. it seems to me that calling it 'blame' is pejorative. It might be the reason, but it's a good reason. There was inequality of opportunity before, and now improvements for women mean that it's time for another push to see how everyone's talents can be developed and utilised.
Interestingly this week I was talking to a post doctoral woman from the Far East who probably would be better off divorced, but she couldn't go back to her own country to work as she fears that as a divorced woman she'll not have a fair chance.
