>> 2. “Husbands should work, wives should stay at home”.
Gadol > Unless, as is frequently the case, the wife is smarter than the husband and can earn 2x or 3x as much so he can stay home, take care of the kids and learn.
If she is smarter, why would she not let her husband work, both enjoying her time with kids and letting the husband take credit for supporting the family
Note that generally divorce rates are higher in families where “smart” women out-earn their husbands. See how “smart” Ms. Harris used men for career advancement and how long it took her to find her bashert.
I am not saying like the other guy that staying home is a mitzva, but it definitely a reshus.
