Why would said wealthy, hard-working, and fit husband not just hire a maid?
Besides, it's often not just about the fact that someone has to do household labor. A lot of women are realizing that said ideal husband somehow expects their partner to clean up after them, essentially taking over the role of his mother. This is despite both parties often having a full-time job.
A lot of men demonstrate a form learned helplessness, and pretend they are unable to do even the most minimal form of household labor - often including things as trivial as putting the dishes they used in the dishwasher, or putting dirty laundry in the hamper. This needlessly complicates what should've been a trivial chore, and breeds resentment.
A commonly-heard sentiment is that women feel like they have to care for their husband as if he is another child. Their husband expects them to act as his mother and a maid in one. I am not really surprised that this is a turn-off.
