How equity is creating more work for families

I was reading an article on the internet about how the roles in relationships after marriage are becoming more equal, yes more difficult for families. The roles in the house hold are evening out with a male doing approximately an hours more worth of work at the house in a week, while the woman's fell approximately a half hour. With this being said, we are coming closer and closer to equity in the work place every day. Women are working in the field a lot more than they were in the 50's. This is causing them to spend less time together, and creating a bit more stress in relationships. The woman still spends more time doing "house work" than the man, but again it is equaling out.
I believe that this is a good thing depending on the relationship and the career field. Minor details matter when dealing with a statistic like this. I believe with equity comes a better understanding of each others roles in the relationship and can lead to a healthy relationship. I'm not saying it would be less stressful, but  an understanding relationship is important to success.
