Xenia, haven't read every post you've put on here, but you do seem to be a bit of a one for generalisations.
For example, all those women who "never really do get back to proper careers in full time jobs with promotion prospects". Maybe not all women want to climb the greasy rungs of the corporate ladder, working long hours for fat pay packets. Even before I had a kid, I had opted out of a big company lifestyle and had taken a job that offered me more less stress, more free time, and (what I think) is a better quality of life. Of course, this affects my earning potential, but I still have the means to live comfortably.
It's horses for courses, but you imply that women are missing out by not persuing the sorts of careers that entail long-hours and (possibly) material gain. At the end of the day, many women, and men, may find the hands-on business of bringing up their children deeply satisfying.
Surely the issue here is about acknowledging the huge contribution that stay at home parents make to the economy, in the way that they nurture and bring up citizens who are well-grounded, balanced individuals. (Not to say that working parents aren't doing this - they have just chosen to employ other adults to do this job for them: childminders, nannies, nursery staff etc.)
The OP's husband believes that her contribution to their life is minimal - otherwise he wouldn't treat her with so little respect. IMHO, he sounds like an ass and needs to learn a lesson. Sadly, he sounds like someone who is so full of his own self-importance, that it would be hard to persuade him to change his viewpoint.
FWIW, when I was younger, I was in a relationship with a man who earnt twice what I did. We had no children but co-habited. He whittled away my self-esteem and happiness, and one of the things he once told me was that I had to do the majority of household chores to compensate for the lack in my financial contribution. Eventually I left him.
You cannot run a relationship on a tit-for-tat basis - unless you are running a business. If that is what your relationship has been reduced to, perhaps it is time for a rethink.
Good luck Shout, and anyone else in a similar position.
