Yes, I find this idea that the husband is "supporting" the wife falls right into "wife work is without value" idea. When my kids were small, my husband had a job on a remote island, so I was alone 6 months of the year. I didn't really work at that time other than doing some childcare (which IMO was great value for the community at large though it didn't pay that well, but it meant two young kids essentially spend their pre-school years in a home environment. It also allowed me to homeschool for the early years for my own kids which was really positive for them.) Would this have suddenly become valuable work if I'd been a nanny being paid during that time?
There are lots of jobs like this where one person will not be able to take on half of the childcare or daily home work, the military, trucking, sailors (what my dad did, again gone half the year) and then others with weird shifts like police, or even in some cases jobs with super high demands like law (not always but in some cases for sure.) Is the idea only unmarried people with no kids get into these kinds of careers?
I always felt that what was going on was that the work of myself and my husband produced the income from the one job.
Now that the kids are older, I'm in a somewhat new career as I felt that I was getting too old to go back to the military, and busy, my husband has a more relaxed role often working from home, so he does a lot more managing the kids day, and the house, than I do. I don't feel like I am now suddenly contributing more, if anything the opposite, I feel less essential to the functioning of the family unit.
