REading the OP, I was going to say "Yes, it is just you".
Having now read 8 pages, I see it isn't just you, but I still think YABVU to generalise up from your dp to 1/2 the adult population. 
Once you got on to the bit about "superior or well honed skills" you are beginning to sound rather deranged, tbh.
Although I am aware we are all different on here, and one of the things I do love about MN is the variety of experience and the variety of lives we all lead, what you are describing is SO FAR from any world I recognise, it sounds ludicrous.
As so many have said, my dh and I cam into our relationship as equal partners, and we still live like that. We both have time to ourselves to choose what we do with. Even when working 60 hrs a week when dc1 was born, or later when we had 3 small dc, were broke, and no family help - and yes, we were knackered and struggling - we still made sure even if it was a couple of hours a fortnight, we each ring fenced a little bit of time to be ourselves in some way.
I do find it odd when people don't have any interest outside work and being at home, but, although that wouldn't be for me, I can still see that is a different choice for a different person and I wouldn't see one person and then think "all women do this" or "all people under 30 do this" or "all people with the letter a in their name do this", I'd think that one person acts like this.
