Apparently ABC is doing a series. Here's the second part. (Love that woman's hair in the video!)
After seeing this one, the thing that struck me as odd this time was that this is some kind of shocker. I think people my age, hopefully, tend to expect that relationships are a partnership. Granted, we all wish we could be Gonch, but I don't know any dudes my age who wouldn't enjoy being a "stay at home dad" or whatever. All of the most solid relationships I know generally involve absolute bidirectional respect, so why should it be any different in the distribution of roles?
I think the gender roles are blurring a lot more for those growing up in the 70's and later. Most people my age are pretty much through with child rearing and those I know were not in a 50/50 relationship.
That's not to say there were not men who took an active role in child rearing or housework, or women who were not breadwinners...but it seemed the gender roles were still there for the most part even if a woman worked.
I think as women became more career minded, roles simply had to change. When two people work, duties had to be shared. And it became a more positive thing when men took an active role in child rearing instead of the stereo-typical "Tim Allen cave man response".
I know I raised Ian to take a more equal role in relationships so it's just a natural thing for him (although I still say his house cleaning skills suck).
