Sure. I am not advocating long term homemakers in today's world. I think that women including moms going to work is good development. But also, I would rather be the one going to work then the one at home. I was at home for some time so I can compare the two - unless job is really shitty it is better then completely pointless day after pointless day. But I also get how easily ressentment on other side settle too when job is not perfect.

Today it is done either as a value thing (e.g. conservative Christian who believe this is morally right) or for convenience - you actually can't work 40+ hrs plus half of nights/weekends while doing half childcare. Staying at home allows partners career to be unaffected by home.

When couple decide they want to split things that way and we're like that for long years, then it makes sense that the one whose career and salary is benefiting pay the other one who lost employemen possibilities.

I have however never claimed the above is reasonable or preferable split at all ( unless you both have 4 kids or something). I am all for moms working and for partners to share both household work and both earn.
