What I see in the article is that the devide is between professional and social settings.
In the educational or professional space lots has been done and a lot of progress has been made, so much so that the young women interrogated didn’t feel like sex was an obstacle in those areas.
In the social, or romantic sphere though things still seem largely unchanged with men and women still in very classic gender roles.
I’m going to go out on a limb here and say that if things haven’t moved as much in these spheres, it’s because there’s less pressure to achieve equality here. This could be due to the fact that inspite of the issues women face there is still an advantage to their place in social circles and romantic relationships and as such feminism hasn’t touched on them as much, or it could be that some of the issues have a more biological component that we will need to accommodate and compensate for rather than trying to simply level the playing field.
