was the filmmaker trying to make a point about the husband being the stay at home dad and not letting her stay home for a day more. if he had a job instead of her / or just let her take one more day off she wouldn't have been at the bank during the robbery. he seemed like a loser.

I think it's just one of the super specific and non-stereotypical details / idiosyncrasies / background stories Zahler comes up with in his scripts and novels to flesh out a new character in a very short amount of time, enough so that you feel the impact when they go through the meat-grinder (sometimes as early as 5 minutes after they've first been introduced, as is the case for Jennifer Carpenter's character). He's quite good at that.
Its not that, he said "you make more money than me" to her
Meaning, he did used to have a job, but he gave it up to be a stay at home husband.
Equal rights and all that, that's the point he was making, if anything
Maybe the point is men/husbands go out into the world, while a housewife gets to stay at home safe with everything provided for her, and role reversed it,
And really just thinking about it, he really came of as a chick, with all the things he said, so pretty sure the directors/writers were going for a role reversal
Also the scene in the chiefs office earlier. they were talking about how shit society is nowdays, and the media and all the PC shit that exists.
So the production team took a principled approach to their social theories principles, and role reversed the male and female charchters
You are right, women would carry on losers if they were in the bodies of men, and still acted like females do
